(OL) and Stop.
Start/Stop Switch Panel mounted. Used to START or STOP the drive.
Main Speed Potentiometer Panel mounted. Provides adjustment of motor speed.
Jumper Selections
Speed/Torque mode, Timed Current Limit (TCL), or
Non Timed Current Limit (NTCL), Armature Voltage
Feedback or tachometer Feedback, (T, 90, 180),
Tachometer Voltage level, (50V, 20/30V, 7V), if
Tachometer is used.
Adjustable Trimpots
For adjusting settings for Minimum Speed (MIN),
Maximum Speed (MAX), Current Limit (CL), IR
Compensation (IR), Acceleration (ACCEL),
Deceleration (DECEL), Timed Current Limit (TCL)
and Jog Speed (JOG).
TABLE 2 – SELECTABLE JUMPERS (See Section 6, on page 23)
Feature Description
J1, Speed / Torque Mode Jumper. Refer to
Section 6.1, on page 23.
In SPD position, the motor speed is adjustable in
accordance with the main speed potentiometer setting.
In TRQ position, the motor torque is adjustable in
accordance with the main speed potentiometer setting.
J2A, J2B, Input AC Line Voltage. Refer to
Section 6.2 on page 26. Selectable for 115VAC or 230VAC. Factory Set for
230VAC.
J3, Armature Voltage or Tachometer
Feedback. Refer to Section 6.3 on page 26.
Factory set to 180V for Armature Voltage Feedback.
J4, Armature Current Feedback Scaling.
Refer to Section 6.4 on page 27.
Selectable for 2.5A, 5A, 7.5A or 10A. Factory Set (10).
J5, Current Limit Mode. Refer to Section 6.5
on page 27.
In the TCL (Timed Current Limit), motor overload
protection is active. In the NTCL (Non Timed Current
Limit position), drive will run in current limit mode. In an
Overload condition, drive will trip on OL. Armature fuse
may clear.
J6, Tachometer Voltage. Refer to Section
6.6, on page 28. Selection for tachometer voltage in Volts/1000 RPM.
Based on maximum motor speed.
J7, Analog Speed Reference Signal Input
Voltage. Refer to Section 6.7, on page 29.
Factory set to 10V for maximum speed. May be set to
5V for maximum speed. Speed range adjustable with
MIN and MAX speed trimpots.
