Definition

Stop Pedestal Voltage

Stop Pedestal Voltage is the percentage of line voltage applied to the motor after a stop

 

command. Programmed as parameter 16 or as Stop Pedestal in Basic Menu.

Stop Time

Time in seconds after a stop command to ramp down the motor voltage (Stop Time 1 or 2)

 

Stop Time 1 with low voltage ramp active. Stop Time 2 with no low voltage ramp.

 

Programmed as parameter 17 or as Stop Time in Basic Menu.

 

 

Stop Smoothing

Adjustable voltage ramp for smooth deceleration. Motor current is monitored and stop

 

smoothing will continue until the Start Pedestal value is reached.

 

Programmed as parameter

 

 

Run Voltage

Full voltage or Running Voltage

Start Pedestal Voltage

Start Pedestal Voltage – end of stop smoothing and beginning of low voltage ramp to zero

 

volts (if low voltage ramp is active). Programmed as parameter 11 or as Start Pedestal in

 

Basic Menu.
