Error cause
M S
972
Line failure
Cause:
A phase failure occurs during motorised travel and a reset is triggered.
No error is generated during regenerative travel
Remedy:
Check the 3 phases of the supply voltage (measure L1, L2, L3 to PE)
●
975
DC: U > 850V
Cause:
The DC-link voltage rises to more than 850 VDC during travel or when
stopped
Remedy:
Check the
“
A_NEG
”
parameter in the
“
Deceleration
”
menu and
reduce if necessary
Check the connection and function of the brake chopper / brake resistor
In the
“
Rotary encoder & BC
”
menu, check the
“
BC_TYP
”
parameter
Compare the displayed value
“
U_DC
”
in the
“
Brake Chopper
”
info menu with
the measured value at the DC+ and DC- terminals (measuring range 1000
VDC, ATTENTION: High voltage). If the voltage displayed deviates by more
than 5%, there is a defect in the device. If the measured voltage is greater than
620 V, the line voltage is not compliant with the standards
Switch the ZAdyn off and back on
Check the size of the Brake-Chopper / Brake-Resistor,
●
976
STO: Temp. alarm
Cause:
The temperature in the area of the STO safety circuit exceeds 75
degrees Celsius
Remedy:
Check the function of the unit fans
Ensure an ambient temperature of less than 55 degrees Celsius
Switch the ZAdyn off and back on
●
980
SW error (zm)
Cause:
Internal error, unknown state
Remedy:
Switch the ZAdyn off and back on
Perform a software update
For persistent occurrence: Please contact ZIEHL-ABEGG Customer Service
●
981
SW error (zm cc)
Cause:
Internal error, unknown travel curve computer state
Remedy:
The error can only be reset by switching off the ZAdyn
Perform a software update
For persistent occurrence: Please contact ZIEHL-ABEGG Customer Service
●
982
SW error (T>4.5ms)
Cause:
Internal device error, maximum cycle time for internal calculations
almost reached
Remedy:
Perform a software update
For persistent occurrence: Please contact ZIEHL-ABEGG Customer Service
●
990
SW error (Stacktop)
Cause:
Internal ZAdyn error
Remedy:
Perform a software update
For persistent occurrence: Please contact ZIEHL-ABEGG Customer Service
●
991
SIO: Timeout
Cause:
Communication between the motor management processor (MOP)
and the application processor (APP) interrupted
Remedy:
Check EMC-compatible installation (screening, etc.)
For persistent occurrence: Please contact ZIEHL-ABEGG Customer Service
●
994
MOP: Timeout 2
Cause:
Communication between the motor management processor (MOP)
and the application processor (APP) is interrupted when stopped
Remedy:
For persistent occurrence: Please contact ZIEHL-ABEGG Customer
Service
For sporadic occurrence: Check EMC-compatible installation (screening, etc.)
●
997
SW error (MOP)
Cause:Cause:
Internal motor management processor (MOP) error
Remedy:
Perform a software update
For persistent occurrence: Please contact ZIEHL-ABEGG Customer Service
