Pr.112, Pr.113, Cooling Fan Control | Delta Electronics VFD-M

Chapter 4 Parameters

Note: From the diagram shown below, the original setting accel/decel time will be for reference

when the function of the S-curve is enabled. The actual accel/decel time will be determined

based on the S-curve selected (1 to 7).

Pr.112	External Terminal Scanning Time
	Settings 01 to 20

Unit: 2msec

Factory Setting: 01

This function screens the signal on I/O terminals for CPU malfunctions due to external

transients. A setting of 02, makes the scanning time to be 2 x 2 = 4 msec.

Set Pr.77 to 02 before changing settings in Pr.112.

Pr.113

Restart Method after Fault (oc, ov, BB)

Factory Setting: 01

Settings 00 None speed search

01Continue operation after fault speed search from speed reference

02Continue operation after fault speed search from Minimum speed

This parameter is used to select the restart method after certain faults.

Pr. 114

Cooling Fan Control

Factory Setting: 02

Settings 00 Fan Off when the drive stop after 1 Min

01AC Drive Runs and Fan On, AC Drive Stops and Fan Off

02Always Run

03Reserved

Pr. 115

PID Set Point Selection

Factory Setting: 00

Settings 00 Disable

01Keypad (based on Pr.00 setting)

02AVI (external 0-10V)

03ACI (external 4-20mA)

04PID set point (Pr.125)
