TD Series Digital Solid State Soft Starter 48 - 1250A
F018 = Max Current Limit of Ramp 2
Factory Setting = 350%
Range = 200 - 600%
Sets the maximum motor current that the TD Starter will allow during
ramp 2. (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). Current
percentages are based on the Motor FLA as programmed in F001.
Once the motor has reached full speed, the current limit feature is
inactive.
Section 5.5.3 Jog Mode
Continuous use of the Jog feature — either the voltage type (F019) or
the current type (F021) — risks thermal motor damage or nuisance
tripping.
The Jog Function is another user optional feature and is controlled by closing the
input on TB4 Pins 1 and 2. If this input is left open, the TD will ignore all Jog
settings. The Jog feature provides an output from the SCRs only while this input
is closed. It will not continue ramping to full acceleration. This feature can Jog the
motor at either a preset Voltage or a preset Current.
Selection of either Voltage or Current Jogging follows the selected Ramp Profile.
The Jog mode is determined then by F010 above, and whether you have selected
ramp 1 or ramp 2. See the table below for Function numbers relating to the Jog
Function in each Ramp Profile.

F019 = Voltage Jog
Factory Setting = 50%
Range = 5 - 100%
Sets the voltage level of the Jog feature typically is used to check
rotation, alignment, or to slowly move a load into position. Jogging at a
set voltage has no current control so the duration of the applied voltage
must be limited to prevent excessive motor heating.
F020 = Time of Voltage Jog
Factory Setting = 10 seconds
Range = 1 - 20 seconds
Set to minimize motor heating during a voltage jog. This setting is the
maximum allowable time for jogging the motor.
F021 = Current Jog
Factory Setting = 150%
Range = 100 - 500%
Sets output of a current Jog. The jog feature is typically used to check
rotation, alignment, or slowly move a load into position.
