If the drive is to be configured in fixed boost mode (Pr 41 = Fd or SrE) with catch a spinning motor software enabled, an autotune (see Pr 38 on page
47) must be carried out to measure the motor’s stator resistance beforehand. If a stator resistance is not measured, the drive may trip on OV and
OI.AC while trying to catch a spinning motor.
dig: Digital input
th: Motor thermistor input, connect as per diagram below
Fr: Frequency input. See Commander SK Advanced User Guide.
Fr.hr: High resolution frequency input. See Commander SK Advanced User Guide.
Figure 6-11
Trip resistance: 3kΩ
Reset resistance: 1k8
If Pr 34 is set to th so that terminal B7 is used as a motor thermistor, the functionality of terminal B7 as set-up with Pr 05, drive configuration, will be
disabled.
n=0: At zero speed

This parameter is automatically changed by the setting of Pr 12. When Pr 12 automatically controls the setting of this parameter, this parameter
cannot be changed.
A change to Pr 35 is set by pressing the MODE key on exit from parameter edit mode.
See the Commander SK Advanced User Guide.
Fr: Voltage proportional to motor speed
Ld: Voltage proportional to motor load
A: Voltage proportional to output current
Por: Voltage proportional to output power
USEr: User programmable
A change to Pr 36 is set by pressing the MODE key on exit from parameter edit mode.
See the Commander SK Advanced User Guide.
