• The parameters n067, n068, and n069 are used for torque compensation.
• It is usually not necessary to change the default-set values.
• Set
n067 to a larger value if the wiring distance between the Inverter and motor is long and a smaller
value if the motor vibrates.
• Set
with n068 the coil resistance of the motor and n069 the core loss of the motor if the coil resistance
and core loss are known. The parameters n068 and n069 will probably make the torque boost function
more effective.
n070 Decelerating Stall Prevention Selection
Setting range 0, 1 Unit --- Default setting 1
• Select with n070 a method to process the overvoltage error of the Inverter decelerating the motor.
Set Values
Set value Description
0 Inhibits deceleration stall prevention from functioning.
1 Permits deceleration stall prevention to function.
Note 1. Be sure to set n070 to 0 if the Braking Resistor Unit is connected to the Inverter , otherwise the
Braking Resistor Unit will not work.
Note 2. The
Inverter will automatically extend time to decelerate the motor so that no overvoltage er -
ror will result if n070 is set to 1.
