(G) Control parameters

Purpose
To set the starting torque manually
To set the motor constant
To select the V/F pattern matching the
application
To improve the torque in a low-speed range
To perform energy saving operation
To use a special motor
To compensate the motor slip amount when
replacing an SF-JR motor with an SF-PR
motor
To adjust the motor braking torque
To coast the motor to a stop
To use the regeneration unit to increase the
motor braking torque
To operate the inverter with DC power supply DC feeding mode
To avoid overvoltage fault due to
regenerative driving by automatic
adjustment of output frequency
To decrease the deceleration time of the
motor
To select the control method
To secure the low-speed torque by
compensating the slip of the motor
To adjust the speed control gain
To adjust the torque control gain
To stabilize torque feedback signal
To suppress the machine resonance
To adjust the speed gain for Advanced
magnetic flux vector control
5.13.1 Manual torque boost
V/F
V/F
V/F
Voltage drop in the low-frequency range can be compensated, improving reduction of the motor torque in the low-speed range.
• Motor torque in the low-frequency range can be adjusted according to the load, increasing the motor torque at the start up.
• By using the RT signal, it is possible to switch between 2 types of torque boost.
