PROGRAMMABLE PARAMETERS
72 EMX4i User Manual 710-14888-00C
2C – Initial Current
Range:
100% - 600% FLC
Default:
200%
Description:
Sets the initial start current level for current ramp starting, as a
percentage of motor full load current. Set so that the motor
begins to accelerate immediately after a start is initiated.
If current ramp starting is not required, set the initial current
equal to the current limit.
2D – Current Limit
Range:
100% - 600% FLC
Default:
350%
Description:
Sets the current limit for constant current and current ramp
soft starting, as a percentage of motor full load current.
2E – Adaptive Start Profile
Options:
Early Acceleration
Constant Acceleration (default)
Late Acceleration
Description:
Selects which profile the EMX4i will use for an Adaptive Control
soft start.
NOTE
The EMX4i will apply the current limit on all soft starts, including adaptive
control. If the current limit is too low or the start ramp time (parameter 2B)
is too short, the motor may not start successfully.
2F – Kickstart Time
Range:
0 – 2000 milliseconds
Default:
0000 milliseconds
Description:
Sets the kickstart duration. A setting of 0 disables kickstart.
2G – Kickstart Level
Range:
100% - 700% FLC
Default:
500%
Description:
Sets the level of the kickstart current.
CAUTION
Kickstart subjects the mechanical equipment to increased torque levels.
Ensure the motor, load and couplings can handle the additional torque
before using this feature.
2H – Jog Torque
The EMX4i can jog the motor at a reduced speed, which allows precise positioning
of belts and flywheels. Jog can be used for either forward or reverse operation.
Range:
20% - 100%
Default:
50%
Description:
Sets the current limit for jog operation.
