VFD-M Series

5-61

Pr. 140

External Up/Down Selection

Factory Setting: 00

Settings 00 Fixed Mode (keypad)

01 By Accel or Decel Time

02 Reserved

 This parameter is used to change the Master Frequency externally with the Multifuction

Input Terminals. If any two parameters in the group Pr.39-Pr.42 are set to 14 and 15, and

Pr.140 is set to 01, the up/down frequency operation is initiated as the contact closes and

according to the time of acceleration/deceleration.

Pr. 141

Save Frequency Set Point

Factory Setting: 01

Settings 00 Not Save

01 Save

 This parameter is used to save the frequency setting before powering off.

Pr. 142

Second Source of Frequency Command

Factory Setting: 00

Settings 00 Keypad Up/Down

01 AVI (0-10V)

02 ACI (4-20mA)

03 RS485

04 Keypad Potentiometer

 This parameter changes the source for frequency command by using any Multifunction

Input (Pr.39-Pr.42, setting= 28).

Pr. 143

Software Braking Level

Unit: 0V

Settings 115V/230V series 370 to 450 Vdc Factory setting: 380.0

460V series 740 to 900 Vdc Factory setting: 760.0

575V series 925 to 1075 Vdc Factory setting: 950.0

 This parameter sets the level for the dynamic braking to operate. The setting value must

be higher than the steady-state DC BUS Voltage to prevent the braking transistor from

having a 100%-duty. At 100% duty the transistor and resistor will most likely fail.
