Troubleshooting
The following table gives an overview of the most common errors and the possible causes.
No.
Symptom
Cause
1
LED "Power" (green left) is
not lit
a) Power supply (ground at pin 4 of X1, +15 to +75V at pin 5 of X1,
right) not connected or wrongly polarized.
b) Short circuit between switch signals (X3) and ground
2
LED "Network Carrier"
(green, left) is not lit
a) Network cable is not connected, switch is switched off
b) wrong cable (crossover?)
3
LED "Network Traffic"
(yellow, right) does not flash

4
LED "Ready" (green right)
does not light up
a) ChargePump signal not assigned, or module is not connected
b) Software not started or running in demo mode
5
LED "Drive Fault" (red left)
lights up
Not all power amplifiers are connected or not all are supplied with
voltage.
6
LED "E-Stop" (red right)
lights up
a) The emergency stop switch (X2 Pin 5 and 6) is not connected or
pressed.
b) The power supply is not sufficient or the 12V output is overloaded
(maybe fans with too high power consumption connected?)
7
Relays do not switch
a) yellow LEDs light up, but relays do not switch: see 6a
b) yellow LEDs do not light up: Pin assignment of the outputs in the
software not configured correctly
8
Motors do not turn
a) green LED "ChargePump" is not lit: see 4
b) Power amplifiers are not connected correctly
9
only for leadshine power
amplifiers:
Motors have no holding
torque at standstill or start up
jerkily
Current reduction signal is not required and must be cancelled
