EN921 - Variable Voltage w/ PI Power/Current Control

Voltage Control

[Volt Incr Time]

This value determines the time it will take the drive to ramp
from 0 Volts to [Maximum Voltage] when [Control Select]
is set to “Variable Voltage”. The rate determined by this
value and [Maximum Voltage] is linear.

[Volt Decr Time]

This value determines the time it will take the drive to ramp
from [Maximum Voltage] to 0 Volts when [Control Select]
is set to “Variable Voltage”. The rate determined by this
value and [Maximum Voltage] is linear.
