YC: Foldback Features

YC parameters set Output Current Limit function.
■
Output Current Limit
The Output Current Limit function sets the current limit of motor. This function prevents long-term overload
conditions of motor when there is bearing degradation.
The drive will try to decrease the frequency reference to limit the output current. Parameter YC-02 [Current Limit]
sets the current limit setpoint. When the motor current increases to more than the setpoint, the drive will decrease the
output frequency.

YF: PI Auxiliary Control

PI Auxiliary Control lets the drive control pressure when the PI Auxiliary Level is adequate. When the PI Auxiliary
Control Level decreases to the PI Auxiliary Control Setpoint set in parameter YF-03 [PI Aux Control Setpoint], the
YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
Sets the PID Setpoint as specified by the Multi-Setpoint digital inputs.
Sets the PID Setpoint as specified by the Multi-Setpoint digital inputs.
Sets the function to enable or disable the output current regulator.
Sets the current limit.
