software releases of SIMODRIVE POSMO A.
The complete list is updated corresponding to the Edition of the

corresponds to the software release of SIMODRIVE POSMO A
documented here.
The individual faults and warnings are not designated as a function of
the software release.
Version: 05.03.02
Overvoltage
The load voltage has exceeded 35 V (75 W motor) or 60 V (300 W
motor).
When braking, the braking energy is excessive which causes an inad-
missible increase in the load voltage.
Provide regenerative feedback protection.
Remove cause, set STW.7 = 1/0 and STW.0 = 0/1
Pulse suppression
Undervoltage of the load current supply
The load voltage has fallen below 17 V.
The load power supply is overloaded.
SITOP: The load voltage was powered-down when braking due to over-
voltage.
The following applies as of SW 3.0: this fault only occurs if the drive is
to be switched from follow-up mode to control mode. If no enable sig-
nals are set in the control word and only the power supply to the elec-
tronics is switched on, the alarm "Undervoltage load power supply" is
signalled.
This alarm automatically disappears when the load power supply is
switched in.
The response to the fault can be set with P56.14.
Increase load power supply rating.
SITOP: Provide regenerative feedback protection.
Remove cause, set STW.7 = 1/0 and STW.0 = 0/1
Pulse suppression
