4-2 Function Mode „ PID Comparison Function •This function outputs a signal when detecting that the PID feedback value exceeds the set range. •Allocate 07 (FBV) to any of multi-function output terminals P1 and P2 (C021 and C022) or relay output terminals MA and MB (C026). •Set the upper limit in C052, and the lower limit in C053. When the PID feedback value falls below the lower limit, the terminal is turned on. The ON status remains until the value exceeds the upper limit. •The output signal is turned off while output is shut off (during stop or FRS, etc.). •Helps control the number of fans and pumps.
AVR Function 4 •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 that set in the motor voltage selection. Functions •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). 4-21 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.
