Description of power section parameters
Parameters
Response to ext.
fault index 9729.16
Factory setting: EMERGENCY STOP / WAITING
The fault is only triggered in the ENABLED inverter status. Index 9729.16 is used to
program the error response that is triggered by an input terminal programmed to "/EXT.
FAULT".
Response to mains
phase failure
index 9729.4
Factory setting: DISPLAY ONLY
The line input phases of the MOVIGEAR
®
unit are monitored for phase failure. 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 increases drastically in case of a phase failure.
The DC link voltage is monitored at a time interval D
t
= 1 ms for dropping below a
minimum voltage level that depends on the rated supply voltage of the unit.
The result is the following nominal guide value for detecting a phase failure:
• 50 Hz mains: Approx. t
max
= 3.0 s
• 60 Hz mains: Approx. t
max
= 2.5 s
The programmed response is activated when a line phase failure is detected.
Response to TF
signal
index 9729.9
Factory setting: EMERGENCY STOP / WAITING
Index 9729.9 programs the error response which is triggered by the temperature sensor
monitoring of the TF or TH which may be installed in the motor winding.
Manual reset
index 8617.0
Setting range: YES / NO
YES: The error in MOVIGEAR
®
is reset. Index 8617.0 automatically reverts to NO after
the reset. Activating the manual reset does not have any effect if there is no error
present.
NO: No reset.
[7] STOP / WAITING
The drive is braked along the set stop ramp t13. The output stage is
inhibited once the stop speed has been reached and DynaStop
®
(if
installed) is activated. The error is signaled immediately. The error is
signaled via the terminal, if programmed. The ready signal is removed.
The drive restarts without a re-initializing the unit if the error is
eliminated by an internal procedure or an error reset.
