P504 Synchronous encoder monitoring
Setting range: On/Off
• Setting "on:" A wire break between the device and synchronous encoder will be
detected directly when using sin/cos encoders and TTL encoders. In the case of a
defective connection, the error message "A1.F14" (encoder) is displayed. The
error message is also generated in the inhibited state of the device.
• Setting "Off": A wire break between the device and synchronous encoder is not
detected directly. If the speed monitoring is not deactivated, the error message
"A1.F08" (speed monitoring) is displayed in the case of a defective connection.
The error message is only generated in the enabled state of the device.
P52. Mains OFF monitoring
P520 Power off response time
Setting range: 0–5s
Time that the power off must be present for the parameterized power off response to
be triggered.
P521 Power off response
Setting range: Controller inhibit/emergency stop
If a binary input is programmed to "Power on," and as soon as it receives a "0" signal,
the response set here is triggered.
P522 Phase failure monitoring
Setting range: Off/On
The device monitors the line input phases for failure of a phase. If 2 phases fail, the
DC link becomes deenergized. This state corresponds to disconnection from the sup-
ply system. Since the line input phases cannot be monitored directly, monitoring has
to be done indirectly via the DC link ripple. If one phase fails, the ripple increases
drastically.
The DC link voltage is monitored at a time interval Δt = 1 ms for dropping below a min-
imum voltage level that depends on the rated supply voltage of the device.
A phase failure is recognized by the following nominal guide value:
• In a 50 Hz supply system: The voltage level has been underrun approx. t
max
=
3.0s.
• In a 60 Hz supply system: The voltage level has been underrun approx. t
max
=
2.5s.
If a supply phase failure is detected, the output stage is immediately inhibited and the
brake is applied. The error message "A1.F06" (line phase failure) is displayed and the
error response "Immediate switch-off with interlocking" is carried out. The error can
only be reset by a device reset.
