F011 = Initial Voltage of Ramp 1

Factory Setting = 60%
Range = 0 - 100%

Sets the initial voltage of ramp 1 when F010 = 1 or 3. The initial
torque level should be set to provide just enough torque to
make the motor shaft begin to rotate while preventing torque
shock damage to mechanical components.

F012 = Initial Current of Ramp 1

Factory Setting = 200%
Range = 0 - 600%
Sets the initial current of ramp 1 (when F010 = 2 or 4). The
initial torque level should be set to provide just enough torque to
make the motor shaft begin to rotate while preventing torque
shock damage to mechanical components.

F013 = Accel Ramp Time of Ramp 1

Factory Setting = 10 seconds
Range = 1 - 120 seconds
Sets the time between the initial torque (set with F011 or F012)
and either the Max Current Limit (set with F014) or full output
voltage. Set time to enable soft starts without stalls. Also,
consider your motor’s application. For example, centrifugal
pumps may require a shorter ramp time.


ƒ NOTE:

Ramp time is affected by the following conditions:

1. Current limit will extend the ramp time if the motor does not reach

full speed while in current limit mode.

2. Anti-oscillation circuit may shorten the ramp time if the motor

reaches full speed before end of ramp.

F014 = Max Current Limit of Ramp 1

Factory Setting = 350%
Range = 200 - 600%

Sets the maximum motor current that the TE Series starter will
allow during Ramp 1. This limit applies to both voltage and
current-type ramping. Current will be limited to this setting until
either the motor reaches full speed or the over load protection
feature trips (F003).
