Module 9173 Speed-dependent monitoring of the wye/delta switchover
Module 9173 is used to realize a monitoring function dependent on the speed
for the wye/delta switchover of the spindle.
You can use Module 9174 to determine a requirement for switching. Module
9174 supplies the current status for wye/delta operation.
Do not call the module cyclically. A single call is enough for activation,
deactivation or changing the setting.
Call:
PS B/W/D/K <>Mode>
Bit 0 = 0: Monitoring off
Bit 0 = 1: Monitoring on
Useful values for <Mode> include:
xx0 = Deactivate monitoring
001 = Monitoring on, Switchover compatible
PS B/W/D/K <>Switchover speed from wye to delta operation>
PS B/W/D/K <>Switchover speed from delta to wye operation>

Module 9174 Read current spindle status
With Module 9174 you read a the current spindle status in reference to wye/
delta operation.
In order to receive one of the two "Request switchover" status values, you
must activate the speed-dependent wye/delta switchover via Module 9173.
Call:
CM 9174
PL B/W/D <>Status>
0: Spindle in wye operation
1: Request for wye/delta switchover
2: Spindle in delta operation
3: Request for delta/wye switchover

Meaning
Speed-dependent monitoring activated
Faulty call parameters, see error code in
NN_GenApiModuleErrorCode
Invalid shaft speeds were given (e.g. wye
switchover speed >= delta switchover
speed, or shaft speed negative)
