138.32 Peak current derating
Derating of the peak current of the drive is required for special devices (see ZPower unit–
from page 61 and parameter Z138.8– bit 6).
138.34 Torque base value
(from FW version 1.14)
Reference value of the standardized torque parameters.
The torque reference value M
base
was specified the maximum, internal motor torque that
would be available due to a torque current of the same amount as the maximum total cur

nom
Nominal magnetic flux, 100%
Kt Motor Kt factor Z107.44–, in Nm/A
Asynchronous motors or synchronous motors in the field weakening range cannot reach
this torque because of the field current which is required.
The parameter is the reference value of the standardized set value Z18.78–.
