Monitoring of the speed deviation between motor model and external speed
The external actual speed (r1443) is compared with the actual speed of the motor model
(r2169). If the deviation is greater than the tolerance threshold set in p3236, after the switch-
off delay time set in p3238 expires, fault F07937 (Drive: Speed deviation motor model to
external speed) is generated and the drive switched-off corresponding to the set response
(factory setting: OFF2).
