Programmable
outputs not working.
1. Output connected such that it must
source current (pull to positive voltage).
2. OUT-P not connected to power
source.
3. If external power supply is used, the
grounds must be connected together.
4. Improper wiring.
1. Outputs are open-collector and can only sink current -- change wiring.
2. Connect OUT-P to the +5V terminal or to an external supply of up to
24V.
3. Connect the external power supply’s ground to the ZETA6xxx’s ground
(GND).
4. Check wiring for opens, shorts, and mis-wired connections.
Torque, loss of.
1. Improper wiring.
2. No power (POWER LED off).
3. Overtemp, low voltage, or motor
fault.
4. Drive shutdown.
5. Current standby mode enabled.
1. Check wiring to the motor, as well as other system wiring.
2. Check power connection (POWER LED should be on).
3. Check LED status (see Diagnostic LEDs above).
4. Enable drive with the
DRIVE1
command.
5. If more torque is needed at rest, disable standby mode (
DAUTOSØ
command).
Trigger, home, end-
of-travel, or P-CUT
inputs not working.
1. If external power supply is used, the
grounds must be connected together.
2. Improper wiring.
1. Connect external power supply’s ground to ZETA6xxx’s ground (GND).
2.a. Check wiring for opens, shorts, and mis-wired connections.
2.b. When inputs are pulled down to 0V by an external device, connect
AUX-P to +5V supplied or to an ex5-24V supply (but not to both).
2.c. When inputs are pulled to 5-24V by external device, connect AUX-P
to 0V.
2.d. Make sure a 5-24V power source is connected to the V_I/O terminal.
