Delta Electronics VFD-M manual Pr.93, Accel 1 to Accel 2 Frequency Transition, Pr.94, Pr.95, Pr.96

Chapter 4 Parameters

Pr.93	Accel 1 to Accel 2 Frequency Transition
Pr.94	Decel 1 to Decel 2 Frequency Transition

Unit: 0.10 Hz

Unit: 0.10 Hz Factory Setting: 0.00

Settings 0.01 to 400.0 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.

	Pr.96	Count Down Completion
		Settings 00 to 9999		Factory Setting: 00

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.
