Table 4-2 Level 1 Parameter Block Definitions
Description
Allows selection of 15 predefined motor operating speeds.
Each speed may be selected using external switches connected to terminals at J1.
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. Output 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
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: If drive faults occur during rapid Accel or Decel, selecting an S-curve may
Jog Speed is the programmed speed used 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 key. At the terminal strip,close the JOG input (J1-12) then close the FWD or
REV input (J1-9 or J1-10).
In Process Mode, if the Jog key is pressed or J1-12 is closed the drive will 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 in seconds from
zero speed to maximum speed.
Jog Decel Time changes the Slope of the Jog Decel ramp. It is the time in seconds from
maximum speed to zero speed.
Jog S-Curve changes the S-Curve to a new preset value for jog mode.
