Enabled for 1:100 when n8-57 = 1 (high
frequency injection enabled).
Induction Motor: Speed deviation rate
between speed reference value and motor
speed (100% = rated speed, motor
temperature 25C10C) when operating
0.02%
at normal status and when load is stable.
PM motor: Speed deviation when
operating at constant speed may fluctuate
with characteristics and motor temperature
(25C 10C).
