VFD-M Series

5-51

Pr.93

Accel 1 to Accel 2 Frequency Transition

Factory Setting: 0.00

Pr.94

Decel 1 to Decel 2 Frequency Transition

Factory Setting: 0.00

Settings 0.01 to 400.0 Hz Unit: 0.10 Hz

0.00 disable

 These functions are used to change acceleration or deceleration depending on attained

frequency and not by closing contacts on the external terminals. The priority of this

parameter is higher than the time of Accel/Decel 1 and Accel/Decel 2.

Pr.95

Auto energy-saving

Factory Setting: 00

Settings 00 Disable auto energy-saving operation

01 Enable auto energy-saving operation

 When this function is enabled, the AC drive operates at full voltage during speed changes.

At the constant speed periods, drive calculates the optimal output voltage value for the

load and may get it reduced up to 30% below the Maximum Output Voltage.

Output voltage

With energy-saving enabled, the

drive automatically adjust the output

voltage based on the output power

level. The maximum output voltage

reduction is 30%.

Pr.96

Count Down Completion

Factory Setting: 00

Settings 00 to 9999

 This parameter defines the top count value for the VFD-M internal counter. Please also

see Pr.45 and Pr.46 (setting 13). Counting is incremented when the Multi-Function Input

Terminal M1 or M2, makes a low-to-high transition. Upon completion of the count, either

Multi-Function Output Terminal (MO1) or the Multi-Function Relay Contact (RA, RB) will

close.
