(A) Application parameters
NOTE
• When the current averaging range includes the constant-output range, the output current may become large in the constant-
output range.
• When the average current value in the current averaging range is small, deceleration time becomes longer as the output
frequency increases.
• The automatic restart after instantaneous power failure function, fast-response current limit operation, fast-response current
limit operation, shortest acceleration/deceleration, and optimum acceleration/deceleration are invalid.
• Changing the terminal assignment with Pr.178 to Pr.189 (Input terminal function selection) may affect other functions. Set
parameters after confirming the function of each terminal.
• Under the following operating conditions, the load torque high-speed frequency function is invalid:
PU operation (Pr.79), PU + External operation (Pr.79), JOG operation, PID control function operation (Pr.128), remote setting
function operation (Pr.59), orientation control function operation, multi-speed setting (RH, RM, RL signal), torque control,
position control.
• When the average current during acceleration is too small, it may be judged as regeneration, and the maximum frequency
may become the setting of Pr.5.
• The output frequency may change due to the load, so do not get unnecessarily close to the motor or machine.
