Remarks
•
The extended function parameters are made valid by setting "1" in Pr. 30
"extended function display selection". (Refer to page 18)
•
The decimal places of a value of 100 or more (3 digits or more) cannot be set
to be displayed.
6.2 Explanation of the Basic Function Parameters

•
Allows the motor torque in the low
speed range to be adjusted
according to the load.
Make adjustment when stall
prevention is operated when starting.
•
When a constant-torque motor is
used, set the following value:
•
0.1K to 0.75K ......6%
•
