Emotron VS10 - Motor Torque Monitoring

182 01-6203-01R3, CG Drives & Automation
7.7.6. Motor torque monitoring
This function monitors the motor torque during operation.
Preconditions
The motor torque monitoring can only be used for the following motor control types with
speed controller:
• Sensorless control (SL PSM)
• Sensorless vector control (SLVC)
Details
This function sets the internal status signal "Torque limit reached [79]" = TRUE if the
maximum possible torque has been reached.
• The status signal is set irrespective of the response 0x2D67:001 (P329.01) and delay
time 0x2D67:002 (P329.02) set for this monitoring.
•
The user can use the status signal to activate certain functions.  Flexible I/O
configura- tion

• The status signal also serves to set a digital output or a bit of the NetWordOUT1 status
word.

Selection of response to reaching the maximum possible torque.
The selected response takes place if the status signal "Torque limit
reached [79]" = TRUE and the deceleration time set in 0x2D67:002
(P329.02) has elapsed.
Associated error code:

Optional setting of a deceleration for triggering the response selected in
0x2D67:001 (P329.01).
Typical application:
The motor should be driven at the torque limit for a short time with
out
triggering the selected response.
Only after a longer operation (> set deceleration) at the torque limit,
the selected response is to take place.

This parameter serves to implement a statically and bipolarly acting
torque limitation. This can be used, for instance, as overload
protection of the mechanical transmission path/elements starting
at the motor shaft.
This limitation acts irrespective of the torque limitations acting in
uni
polar mode that are set in 0x60E0 and 0x60E1.
