P.O.R.T. Recovery Method FUN 12
LCD Display
LCD Description
Range
Fast Recover Current acceleration ramp from 100% FLA -> 800% FLA with a
ramp time of 1 second.
(Default)
Current Ramp Current acceleration ramp using the Ramp#1 user parameter settings.
Current Ramp 2 Current acceleration ramp using the Ramp#2 user parameter settings.
Ramp Select Current acceleration ramp using the appropriate current ramp
selected by the RAMP Select digital input.
Tach Ramp Speed controlled acceleration ramp. Ramp starts at motor speed
measured at start of recovery and accelerates motor at same slope
(acceleration rate) as a normal tachometer start from zero speed
would do.
Description The PORT Recovery parameter sets how the starter will re-accelerate the motor when power returns.
Tachometer Full Speed Voltage FUN 13
LCD Display
Range 1.00 – 10.00 V in 0.01 volt increments (Default 5.00V)
Description The Tachometer Full Speed Voltage parameter sets the tachometer input voltage at full speed. This value
should be set at full (unloaded) motor speed.
Ex. A tachometer rated at 0.0033 volts-per-rpm is mounted on a 4-pole 1800 rpm motor. Therefore, the FS
Volts should be set to: 0.0033 * 1800 = 5.94 volts.
