These settings are used when the starting torque response delays influence the acceleration/deceleration
times. Normal settings of these parameters are from
0.5 to 2Hz, and should be kept less than 5Hz.
Overcurrent can be avoided by keeping the frequency less than the motor rated slip amount.
During start-up
···The IF - SI:: I frequency setting is instantaneously output.
During stopping
···The output frequency is instantaneously changed to OHz when the IF - E ,-, I frequency
setting
is reached.
