Explanation of the parameters
Parameterization of MOVIPRO

P505 Synchro-
nous encoder
monitoring
Setting range: Yes/No
• No: An open circuit between frequency inverter and synchronous encoder is not
directly detected. In case of a defective connection, error "A1.F08" (speed
monitoring) will be issued in enabled state unless it was deactivated.
• Yes: An open circuit between frequency inverter and synchronous encoder will be
directly detected when using sin/cos encoders and TTL encoders. The error
message "A1.F14" (encoder) will be issued in case of an error. This error will also be
generated in inhibited state.
P52x Mains OFF
monitoring
P520 Mains OFF
response time
Setting range: 0 – 5 s
P521 Mains OFF
response
Setting range: Controller inhibit/emergency stop
If the binary input is programmed to "Mains on", the response set here will be triggered
when the binary receives a "0" signal.
P522 Phase fail-
ure monitoring
Setting range: Off/on
Das MOVIPRO

überwacht die Netzeingangsphasen auf Phasenausfall einer Phase. If
a phase failure is detected in two phases, then the DC link will be de-energized, which
corresponds to a supply system disconnection. Since the line input phases cannot be
monitored directly, monitoring has to be done indirectly via the DC link ripple, which in-
creases drastically in case of a phase failure.
The DC link voltage is monitored at a time interval
∆
t = 1 ms for dropping below a mini-
mum voltage level that depends on the rated supply voltage of the unit.
The result is the following nominal guide value for detection of a phase failure:
• 50 Hz supply system: Approx. t
max
= 3.0 s
• 60 Hz supply system: Approx. t
max
= 2.5 s
Once a phase failure has been detected, the output stage is inhibited and the brake is
applied. The error message "A1.F06" (phase failure) is issued. The error response is
"Immediate switch-off with inhibit". The error can only be remedied by executing a unit
reset.
P53x Motor temperature protection
P530 Sensor type
1
Setting range: No sensor / TF/TH / TF/TH DEU / KTY / KTY DEU (KTY only for SEW
synchronous motors)
Selection of the sensor used for motor protection in parameter set 1.
• TF/TH: Set the response with
P835 Response to "TF signal"
(page 118).
• KTY: Set
P340 Motor protection 1
(page 101) to "ONE servo". The motor model is
now activated. Set the response using
P832 Response to "motor overload"
(page 118).
P531 Sensor type
2
Setting range: No sensor / TF/TH
Selection of the sensor used for motor protection in parameter set 2.
