accuracy at low speed might be sacrificed.
The impacts of 18-00 on the torque and the speed are shown as the following figure:

(2) Slip compensation gain at high speed (18-01)
. In the case of load coupling, it is no need to adjust the accuracy at high speed in the
control using this parameter.
.After 18-00 is adjusted, increase the reference frequency and observe whether the
speed has error. If the speed error exists, you can increae the set value of 18-01 for
compensation.
.Increase the motor rated frequency (01-12 basic frequency ), increase the set value
of 18-01, so as to reduce thespeed error.
.If the speed accuracy becomes poorer due to over high temperature of the motor, it is
more appropriate to use 18-00 and the set value of 18-01for adjustment.
.Compared to 18-00, 18-01 is different because 18-01 is a variable gain value in the full
speed range.
18-01 determins the slip compensation at the motor rated rotation, its principle
calculation is shown as below:
Slip compensation gain= Slip compensation gain at low speed + Slip compensation gain
at high speed* ( frequency reference/Motor rated frequency (01-12))
