Parameter Description
Parameter Description
5.10 JOG Mode (P.15, P.16)
P.15 “JOG frequency”
P.16 “JOG acceleration/deceleration
time”
At the JOG mode, the output frequency is the set value of P.15, and the acceleration/deceleration
time is the set value of P.16.
Parameter Factory Setting Setting Range Remarks
--- zH056~0 zH5 51
0~360s When P.21=0
16 5s
0~3600s When P.21=1
Note: Please refer to Section 4.1 for entering into the JOG mode.
5.11 Stall Prevention (P.22, P.23, P.66)
P.22 “Stall prevention operation level”
P.23 “Offset coefficient for Stall prevention operation level at double speed”
P.66 “Starting frequency for reducing the stall prevention operation level”
The motor speed often fail to closely follow the output frequency when starting the motor or
increasing the target frequency if there is heavy load. Increase the output current to improve the
output torque if the motor speed is smaller than the output frequency. However, the motor torque
will decrease if the difference between the output frequency and the motor speed is too large,
which is referred to as stall.
