Error recognition:
6.11.9 Monitoring of Power Supply Unit and DC-Link Voltage (digital axes only)
At X51 to X59 and X61 the ready signal is available at pin 6.
The signal is reset for the following reasons:
n The connection of K9 to K663 on the HEIDENHAIN interface PCB is not
closed (with SIMODRIVE inverter system)
n Voltage from the unit bus (FR+) is missing (with SIMODRIVE inverter
system)
n Error in the power supply unit (+5 V or U
z
is missing or U
z
is too large)
As soon as the readiness signal is reset, the drive controllers are switched off.
Normally, the error message MOVEMENT MONITORING IN <AXIS> A is output
through the position control loop.
Subsequently, the PWM signal release is switched off by the reset signal.
After the drive controller is switched on with Module 9161, you can use
Module 9162 to interrogate the readiness of the drive controller ((See
“Module 9162 Status request of the drive controller” on page 6 – 145)).
