Description
PRESET
SPEEDS
Preset Speeds
#1 – #15
Allows selection of 15 predefined motor operating speeds.
Each speed may be selected using external switches connected to J1B-11, J1B-12,
J1B-13 and J1B-14.
For motor operation, a motor direction command must be given along with a preset
speed command.
ACCEL/DECEL
RATE
Accel Time #1,2
Decel Time #1,2
S-Curve #1,2
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. Accel Time #2 is accessible in Standard Run 3 Wire and 15
Speed 2 Wire modes only.
Example: Maximum Output Speed =1000 RPM; Preset Speed = 500 RPM, Accel
Time=10 Sec.
In this example, motor will be at 500 RPM 5 seconds after commanded because preset
is half the max speed.
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 or Decel time and provides smooth starts and
stops.
Figure 4-2 illustrates how motor acceleration is changed using a 40% S-Curve.
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,
Accel #2, Decel #2 and S-Curve #2 are associated together. These
associations can be used to control any Preset Speed or External Speed
Command (Pot).
Note: If faults (motor trips) occur during rapid Accel or Decel, selecting an S-curve
may eliminate the faults without affecting the overall ramp time.
JOG SETTINGS
Jog Speed
Jog Speed changes motor speed to a new preset value for jog mode. To cause motor to
operate at Jog Speed the FWD or REV key must be pressed or external command
Forward (J1B 9) or Reverse (J1B 10) The motor will run at jog speed until FWD or
g
Forward (J1B-9) or Reverse (J1B-10). The motor will run at jog speed until FWD or
REV key is released or external command signal is removed. Jog speed can be less
than the minimum speed parameter setting.
Jog Accel Time
Jog Decel Time
than the minimum s eed arameter setting.
Jog Accel Time changes the Accel Time to a new preset value for jog mode.
Jog Decel Time changes the Decel Time to a new preset value for jog mode
Jog Decel Time
Jog S-Curve
Jog Decel Time changes the Decel Time to a new preset value for jog mode.
Jog S-Curve changes the S-Curve to a new preset value for jog mode.
