4-14 Programming & Operation
Power Output Control Board
Description
Allows selection of 15 predefined motor operating speeds.
Each speed may be selected using external switches connected to J1-11, J1-12,
J1-13 and J1-14 when Operating Mode is set to 15 Speed.
For motor operation, a motor direction command must be given along with a preset
speed command.
Accel time is the number of seconds required for the motor to increase at a linear rate
from 0 RPM to the RPM specified in the "Max Output Speed" parameter in the Level 2
Output Limits block. Out ut Limits block.
Decel time is the number of seconds required for the motor to decrease at a linear rate
from the speed specified in the "Max Output Speed" parameter to 0 RPM.
S-Curve is a percentage of the total Accel and Decel time and provides smooth starts S-Curve is a percentage of the total Accel and Decel time and provides smooth starts
and stops. Half of programmed S-Curve % applies to Accel and half to Decel ramps.
0% represents no "S" and 100% represents full "S" with no linear segment.
Note: Accel #1 Decel #1 and S Curve #1 are associated together Likewise Note: Accel #1, Decel #1 and S-Curve #1 are associated together. Likewise,
Note: If drive faults occur during rapid Accel or Decel, selecting an S-curve may
Jog Speed is the programmed speed used during for jog. Jog can be initiated from the
keypad or terminal strip. At the Keypad, press the JOG key then press and hold the
FWD or REV. For Standard Run, close the JOG input (J1-12) then close and maintain
the direction input (J1-9 or J1-10). the direction input (J1-9 or J1-10)
Process Control mode operation is different. If the terminal strip Process Mode
Enable input (J1-13) is closed, pressing the Keypad JOG key (or closing J1-14) will
cause the drive to move in the direction of the error (without pressing FWD or REV). cause the drive to move in the direction of the error (without pressing FWD or REV)
Jog Accel Time changes the slope of the jog accel ramp. It is the time from zero speed
to maximum speed programmed in seconds.
