Fault message
on the display
Cause of message
P-CHECK-UP
Fault: Decel/jerk 4 too high
No plausible travel curve data!
Remedy:
Degrease delay and/or increase jerk4
P-CHECK-UP
Fault: Jerk1 too high
Jerk1 has to be degreased for the parameterized v/n ratio
P-CHECK-UP
Fault: Jerk2 too high
Jerk2 has to be degreased for the parameterized v/n ratio
P-CHECK-UP
Fault: Jerk3 too high
Jerk3 has to be degreased for the parameterized v/n ratio
P-CHECK-UP
Fault: Jerk4 too high
Jerk4 has to be degreased for the parameterized v/n ratio
P-CHECK-UP
Fault: v decel. too high
For the parameterized v/n ratio v decel. is adjusted too high
P-CHECK-UP
Fault: v R max too high
For the parameterized v/n ratio v R max is adjusted too high
P-CHECK-UP
Fault: Accel. too high
For the parameterized v/n ratio Accel. is adjusted too high
P-CHECK-UP
Fault: Decel. too high
For the parameterized v/n ratio Decel. is adjusted too high
P-CHECK-UP
Fault: v R too high
Parameterized ratio v/n and max. permissible speed v R result in a too high output
frequency, which the inverter may no longer generate
P-CHECK-UP
Fault: v N too high
Parameterized ratio v/n and max. permissible speed v N result in a too high output
frequency, which the inverter may no longer generate

Alarm messages on the display
Prior to giving certain fault messages the inverter issues an alarm message. Such an alarm can be recognized by way
of release of the ready relay, LED
READY
on the internal control panel goes out, and LED
ALARM
on the internal
control panel is on.
No fault is given. The alarm is taken back as soon as the respective event is no longer present. If the respective alarm
has been stored, it must be reset by way of inverter resetting, provided that the cause of the alarm is no longer
present.
Fault message
on the display
Cause of message
!! Alarm !!
Motor overtemp.
PTC thermistor at terminal X1:28/:29; motor overloaded; insufficient motor or room
ventilation
!! Alarm !!
Inverter overtemp.
Inverter overloaded; defective fan; coolant temperature too high
!! Alarm !!
Brak.resist. overload
Braking resistor overloaded or resistor too small, lift overloaded; plant efficiency >
70 %; incorrect setting of c.d.f. brake resistor.
