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.
