TABLE 1
ADJUSTABLE TRIMPOTS
Trimpot Range
Description
T-BRK
1
0.2
2.5
Timed Brake Delay (T-BRK):
Allows adjustment of the delay time before the brake engages after the control is put into the stop or brake mode.
Stop or brake is initiated by opening the Enable Switch or Key Switch or by closing inhibit terminals.
Adjustment Range:
0.2 – 2.5 Seconds;
Factory Setting:
1 Second
CL
150
0
200
Current Limit (CL):
Allows adjustment of current limit setpoint. Typically set to 1.5 times the full load current rating of the motor. When
the control is in Current Limit, the STATUS LED will illuminate red.
Adjustment Range:
0 – 200% of Jumper JB Setting;
Factory Setting:
150%
0
IR
4
25
IR Compensation (IR):
Allows adjustment of load compensation for different motors. Smaller motors require more compensation to
overcome losses in armature winding. Typically set by checking No Load to Full Load speed changes.
Adjustment Range:
0 – 25 Volts DC;
Factory Setting:
4 Volts DC
2
DECEL
0.1
15
Deceleration (DECEL):
Allows for controlled deceleration from full speed to zero speed. Decel works with all stop modes except inhibit.
When inhibit is used, the DECEL Trimpot has no effect, output will go to zero in 0.1 seconds.
Adjustment Range:
0.1 – 15 Seconds;
Factory Setting:
2 Seconds
2
ACCEL
0.1
15
Acceleration (ACCEL):
Allows for controlled acceleration from zero to full speed. Acceleration is active in any turn-on condition, including
Enable, Key Switch, or release of inhibit.
Adjustment Range:
0.1 – 15 Seconds;
Factory Setting:
2 Seconds
MIN
0
30
Minimum Speed (MIN):
Sets the minimum speed the motor will run.
Adjustment Range:
0 – 30% Base Speed;
Factory Setting:
0%
RMAX
50
100
Reverse Maximum Speed (RMAX):
Limits the maximum allowable speed in the reverse direction.
Adjustment Range:
50 – 100% Base Speed;
Factory Setting:
100%
FMAX
60
100
Forward Maximum Speed (FMAX):
Limits the maximum allowable speed in the forward direction.
Adjustment Range:
60 – 100% Base Speed;
Factory Setting:
100%
TABLE 2
RUN RELAY OPERATION
Connector P5
Description
Run Relay Output Contacts Selection (P5):
Provides Normally Open or Normally Closed relay output contacts
(use Jumper J8 to select N.O. or N.C. contacts). The Run Relay is engaged when the control is in the Run Mode.
The Run Relay is disengaged when the control is in the Stop Mode or for any fault condition (Main Speed
Potentiometer Fault (open lead), Over Temperature Fault, Overvoltage Fault, Undervoltage Fault, Motor Brake
Fault, Internal Fault (micro failure), and Timed Current Limit.

DIAGNOSTIC LED INDICATORS
LED Description
Power On:
This green LED is illuminated when the Key Switch is engaged.
Status:
Both green and red LEDs are used to indicate control status. See Table 4 on page 3.
