Error cause
M S

ADC:Overcurrent
Cause:
A motor overcurrent has been detected
Remedy:
Check the motor connection for short circuit and earth fault
Check the phase sequence of the motor connection (U->U; V->V; W->W)
Check the connection and function of the rotary encoder (for further informa-
tion, see the
“
Rotary encoder
”
info menu)
Check the absolute encoder adjustment
Check the motor data in the
“
Motor name plate
”
menu
Reduce the
“
SPD_KP
”
parameter in the
“
Control
”
menu
Reduce the
“
K_START
”
parameter in the
“
Start-up
”
menu
For open loop operation (asynchronous operation without sensors):
Con
fi
gure the
Control/UF_ED=On
parameter and then gradually increase the
Control/I_IxR
parameter. Do not exceed a maximum value of 1.5 x nominal
motor current.
●
412
MOT: UVW missing
Cause:
The motor test current was not reached at the start of travel
Remedy:
Check the motor connection and motor cable
Contact ZIEHL-ABEGG Customer Service
●
415
MOT: Current UVW
Cause:
The sum of the currents U, V, W is not equal to 0
Remedy:
Check the motor connection for short circuit and earth fault
●
●
420
MP: Temp. alarm
Cause:
Overtemperature on power unit
Remedy:
Check the function of the unit fan
Check the ambient temperature
Remedy the cause of overheating (reduce on time, check load ratios in the
system, check motor parameters, adjust the absolute encoder on synchronous
machines etc.)
●
431
MP: PWM fail
Cause:
Internal device error, pulse width modulation has been switched off
Remedy:
Check rotary encoder connection
For persistent occurrence: Please contact ZIEHL-ABEGG Customer Service
For sporadic occurrence: Check EMC-compatible installation (screening, etc.)
●
450
MP: Overload
Cause:
The maximum output current of the ZAdyn has been exceeded for
more than 10 s
Remedy:
Check the connection and function of the rotary encoder (for further
information, see the
“
Rotary encoder
”
info menu)
Check motor data
Check the weight compensation
Check opening of the brake (motor)
Check the absolute encoder adjustment
Check the required motor power and unit size
Check that the cabin and counterweight engage easily

DC: U < UDC_MIN
See error 970
“
DC: U > 850 V
”
.
●
471
DC: U > UDC_MAX
Cause:
DC-link voltage has exceeded the maximum voltage during travel
Remedy:
Check the connection, function and design of the brake chopper/-
brake resistor,
In the
“
Power unit
”
menu, check the parameters for
“
UDC_MAX
”
,
In the
“
Rotary encoder & BC
”
menu, check the
“
BC_TYP
”
parameter
In case of poor travel behaviour (vibration), check the
“
SPD_KP
”
parameter in
the
“
Control
”
menu
If the error occurs during deceleration, reduce the
“
A_NEG
”
parameter or
increase
“
R_NEG1
”
in the
“
Deceleration
”
menu
●
