4-2 Function Mode C052 (OFF level) PID feedback C053 (ON level) Time FW ON OFF FBV ON OFF 4 „ PID Feedback Value Monitor •You can monitor the PID feedback value. •The monitor value is displayed as the product of the feedback value and PID scale A075. "Monitor display" = "Feedback value (%)" Ч "A075 setting" Functions „ PID Integral Reset •Clears the integral value of PID operation. •Allocate 24 (PIDC) to any of multi-function inputs C001 to C008. •Clears the integral value every time the PIDC terminal is turned on. Do not turn on the PIDC terminal during PID operation to avoid a possible overcurrent trip. Turn on the PIDC terminal after turning off PID operation.
AVR Function •This function outputs voltage to the motor correctly even if the incoming voltage to the Inverter fluctuates. With this function, output voltage to the motor is based on the voltage set in the motor voltage selection. •With A081 (AVR selection), set whether to enable or disable this function. •Note that the Inverter cannot output voltage beyond that of the incoming voltage. •To avoid a possible overcurrent trip during deceleration, set the AVR selection to "Always ON" (A081: 00). 4-35 Parameter No. Function name Data Default setting Unit A081 AVR selection 00: Always ON 01: Always OFF 02: OFF during deceleration 02 A082 AVR voltage selection 200-V class:
200/215/220/230/240 400-V class: 380/400/415/440/460/480 200/400 Related functions d004, A001, A005 Parameter No. Data Description Note A081 00 Always ON Enabled during acceleration, constant speed , and deceleration. 01 Always OFF Disabled during acceleration, constant speed, and deceleration. 02 OFF during deceleration Disabled only during deceleration in order to reduce the energy regenerated to the Inverter by increasing the motor loss. This will avoid a possible trip due to regeneration during deceleration.
