Meaning
The actual speed value has reached the speed tolerance band specified
via p2164 after a new speed setpoint specification and has not left the band
for the duration of p2166.
The ramp-up procedure is still active after the speed setpoint has been
changed.
| < M ".
d dx
Meaning
The current torque utilization lies below the torque utilization threshold set
in p2194. The drive signals the PLC that the torque setpoint |M
exceed the threshold torque M
The torque setpoint |M | is larger than the threshold torque M
d
can be used to determine whether the motor is overloaded.
| < n ".
act min
Meaning
The actual speed value |n
set in p2161.
The actual speed value is greater than the threshold minimum speed.
