Internal speed limit
Except basic limit, it is also limited by internal
speed command. The internal speed command is
determined by SP1, SP2, and SP3 from DI
inputs.
Note: 1.If many limits occur, the final limitation value will be the smallest value. If the setting
value surpasses the system permission the maximum speed, the actual speed also can limit in the
maximum speed.
P078 Speed limit in torque control

Default
value
Unit
Usag
e
0 ～ 5000 3000 r/min T
 The servomotor running speed limits in this parameter for torque control mode.
 Under light loading can prevent the servomotor from over speed.
 When appears over speed, turns on speed negative feedback to reduce the actual torque, but
the actual speed can be higher than the limit value slightly.

e
1 ～ 5000 100 r/min T
 This parameter can govern the quantity of speed negative feedback if the over speed
appears.
 The smaller the value, the bigger negative feedback and the smaller over speed achieve; the
limiting curve is steeper, but may cause shake if the value is too small.
P080 Position deviation limit

Usag
e
0.00 ～ 327.67 4.00 圈 P
 Set the position deviation range for alarm when the deviation exceeds this parameter.
 Under position control mode, when the counting value of position deviation counter
exceeds the pulses corresponding to this parameter value, the servo driver gives the position
deviation alarm (Err 4).
 The unit is one circle. Multiplying the resolution of encoder with the value of this parameter
can obtain the total pulse number. For example, the encoder has 2500 lines and the
resolution of encoder is 10000. If the parameter value is 4.00, then corresponds to 40000
pulses.
