Safety instructions

Electrical installation must be carried out by a competent electrician!

The motor drive has been designed for fixed installations only.

Do not perform any voltage withstand tests on any part of the motor drive or the tool. Product safety has been fully tested at the factory.

Ground yourself with an anti-static wristband before touching the motor drive (setting jumpers and similar actions) to avoid electrostatic voltage discharge damage to the motor drive.

Always disconnect the power before performing any work on the cabinet.

Warnings

Make sure that all the AC-DC power supplies are properly earthed and that the motor drive cannot come in contact with live mains voltage.

An external emergency stop circuit is recommended.

Before running the tool

Before starting the tool, check that the tool is mounted properly and ensure that the motor drive is installed properly.

The motor drive PCB comes mounted in a DIN-rail holder that can be attached to a standard 35 x 7.5mm EN50022 DIN-rail, but the motor drive PCB can be removed from this holder and mounted using the mounting holes instead. If the mounting holes are used, then it is recommended to use 20 mm metal standoffs and 10 mm M3 screws when mounting the motor drive PCB.

It is recommended to use 10 mm ferrules with plastic sleeve for each wire that is attached to any of the connectors. The wires can then easily be pushed into the connectors and released with the help of a small flat-head screwdriver (3.5 mm blade width, 0.6 mm blade thickness).

Terminal block connections (Firmware v. 3.05 and newer)

Enable-State:

For the sander to be able to operate, terminal block 4 must be connected to a 24V output from the robot/PLC, while terminal block 6 should be connected to 0V on the robot/PLC.

For enhanced safety, the Enable-State output could be set to low if the robot encounters an issue that causes it to stop. This will automatically halt the sanding/polishing head.

The 3 meter, 2-pole cable provided with the cabinet should be used for connecting the enable-state as per the instructions

Vacuum Autostart Module:

Customers can integrate the optional Mirka AutoStart Module (MIA6519011) to enable automatic start/stop functionality for the dust extractor. To do this, connect terminal block 5 to the positive (+) terminal on the AutoStart Module and terminal block 7 to the negative (−) terminal.

Modbus RTU

Modbus RTU over RS-485 is used to communicate with the motor drive. The motor drive is configured as a Modbus RTU slave device and the default slave address is 86. The slave address can be changed if it conflicts with another Modbus RTU slave device.

The J1 connector on the motor drive is used for Modbus RTU communication. A shielded twisted pair cable is recommended and the shield should be earthed only at one point, normally at the master device. The A-pin of the J1 connector is equivalent to RxD / TxD+ and the B-pin is equivalent to RxD / TxD−.

Basic operation for Modbus RTU

The motor drive must be enabled before the tool can be started. The first operation that should be done is to set the motor drive to the Enabled-state. This operation differs starting from firmware version 3.05. On earlier versions a "Drive enabled" command should be sent to the motor drive, while newer versions have the digital pin DI1 allocated as the Enabled-state. It is not mandatory to send the Disabled-state command before removing power from the motor drive.

When the motor drive is enabled the speed set-point value can be written and the state can be set to RUN-state by sending the RUN-state command. This will cause the tool to run at the set-point speed. To stop the tool, set the motor drive to STOP-state by sending the STOP-state command.

It is recommended to continuously monitor the average speed, average current, tool temperature, motor drive temperature and the alarm status flag. This will help to detect if there are any issues present during operation.

Example sequence for starting and stopping the tool (Firmware v. 3.04 and older):

• Write 4 (0x0004) to the "Operation" register, this will set the motor drive to Enabled-state.
• Write 4000 (0x0FA0) to the "Speed set-point" register, this will set the set-point speed to 4,000 rpm.
• Write 1 (0x0001) to the "Operation" register, this will set the motor drive to RUN-state and the tool will start running.
• Write 2 (0x0002) to the "Operation" register, this will set the motor drive to STOP-state and the tool will stop running.
• Write 8 (0x0008) to the "Operation" register, this will set the motor drive to Disabled-state.

Example sequence for starting and stopping the tool (Firmware v. 3.05 and newer)*:

• Set pin DI1 (terminal block 4) to high (15-33 VDC), this will set the motor drive to Enabled-state.
• Write 4000 (0x0FA0) to the "Speed set-point" register, this will set the set-point speed to 4,000 rpm.
• Write 1 (0x0001) to the "Operation" register, this will set the motor drive to RUN-state and the tool will start running.
• Write 2 (0x0002) to the "Operation" register, this will set the motor drive to STOP-state and the tool will stop running.
• Set pin DI1 to low (GND), this will set the motor drive to Disabled-state.

*See chapter "Terminal block connections (Firmware v. 3.05 and newer)" for detailed connection information.

Digital interface

The motor drive can also be controlled via the digital interface instead of Modbus RTU, but with the added drawback that there is no feedback when using the digital interface. To enable the digital interface, the JP12 jumper needs to be set.

Connector J5 is used as input for the digital interface. The input is considered high if a voltage between 15–33 VDC is applied to the input pin. The input is considered low if the voltage is below 12 VDC or if the input is left floating. The GND pin of connector J6 must be connected between the systems. The J6 connector can also be used to provide a 15 VDC control voltage if needed.

Digital interface operations

Please refer to the Speed set-point display table in the Motor drive overview chapter.

Self-test function

While holding down the S1 button the motor drive will perform a quick self-test. The alarm status flag will be set to 6 (self-test running). The indicators D4 and D14 will blink green if temperatures and voltages are within the limits. If the temperatures or voltages are not within the limits then the indicators will blink red.

Reset function

The reset button S2 can be pressed momentarily to reset the motor drive. This is essentially the same as turning the power off and on again.

Factory reset function

The configuration stored in the motor drive can be reset to factory defaults if needed. This will restore the factory assigned Modbus slave address and the last known tool configuration will be reset to factory defaults. Follow these steps to do a factory reset:

1. Set jumper JP15.
2. Press and hold S2 for 5 seconds.
3. Remove JP15.

Write protection

The holding registers for "Device name" and "Slave address" are normally read-only to prevent accidental writes to these registers. If any of these registers needs to be changed, follow these steps:

1. Write 64 (0x0040) to "Operation" register to disable the write protection.

2. Write the new value to "Device name" or "Slave address" holding registers.

3. Write 128 (0x0080) to "Operation" register to enable the write protection.

Safety stop / E-Stop

The motor drive itself does not have any inputs for detecting or reacting to an external safety stop / E-Stop signal. A suitable contactor can be used placed near the motor drive to connect or disconnect the tool cable phase A, B and C wires.

On the fly tool change function

Multiple tools can be used with the same motor drive but only one tool can be connected to the motor drive at any given time. When changing from one tool to the next, follow these steps:

1. Stop the tool by writing 2 (0x0002) to the "Operation" register.
2. Write 16 (0x0010) to the "Operation" register to let the motor drive know that you are intending to disconnect the currently attached tool.
3. Wait 1 second before disconnecting the currently attached tool from the motor drive.
4. Disconnect the currently attached tool from the motor drive.
5. Connect the next tool to the motor drive.
6. Write 32 (0x0020) to the "Operation" register to let the motor drive know that the new tool has been attached.
7. Wait 1 second before starting the new tool.
