Troubleshooting guide

Symptom
Motor drive does not power on.
Tool does not start.
Tool suddenly stops.
Modbus RTU communication is not working.
Profinet I/O gateway communication is not
working.
Digital speed controller interface is not
working.
Indicator D36 is lit red, or the tool speed is
too fast/slow.
Reason
• Motor drive is over 117°C
• Tool temperature is over 134°C
• Excessive load
• Motor drive is over 123°C
• Tool temperature is over 142°C
• Overload condition
Recommended procedures
• Check that 48 VDC is present on J2 and that the polarity is correct.
• Check that the motor drive is in ON-state (D14 is not blinking).
• Check that the motor drive is in RUN-state (D4 is lit green).
• Check the cable assembly for the tool: are the pins properly connec-
ted?
• Check the alarm status flag.
• Check the motor drive and tool temperatures.
• Check if the tool is being overloaded.
• Check that JP1 and JP12 are not set.
• Check the baud rate, parity, stop bits and data bits.
• Check the transmit/receive indicators D29 and D30; these blink when
there is activity on the bus.
• Check that the A-pin and B-pin are connected properly.
• Check whether addition of a terminating resistor (JP2), A-pin pull-
down resistor (JP3), B-pin pull-up resistor (JP4) solves the issue.
• Check the slave address (set the JP13 jumper and use indicators
D2–D3, D17–D22 to read the current address).
• Check that JP1 and JP12 are not set.
• Check the gateway network configuration
• Check the gateway Modbus RTU to Profinet I/O mapping configura-
tion.
• Check the 24 VDC power supply.
• Check the Modbus RTU adapter cable is connected properly.
• Check that JP1 is not set.
• Check that JP1 is not set.
• Check that JP12 is set.
• Check the voltage on a high input, it should be between 15–33 VDC.
• Check the voltage on a low input, it should be close to zero volts.
• Check the GND connection.
• Check C+/C-/P+/P– wiring on J3.
