3.4 TRIMPOT ADJUSTMENTS
• Minimum Speed (MIN) – Sets the minimum speed of the motor. See Section 13.1 on page 29.
• Maximum Speed (MAX) – Sets the maximum speed of the motor. See Section 13.2 on page 29.
• Acceleration (ACCEL) – Sets the amount of time for the motor to accelerate from zero speed to
full speed. See Section 13.3 on page 29.
• Deceleration (DEC/I) – Sets the amount of time for the motor to decelerate from full speed to
zero speed. See Section 13.4 on page 27.
• DC Injection Brake (DEC/I) – When the drive is set for DC Injection Braking (Jumper J7 set to
the “INJ” position), the DEC/I trimpot is used to set the DC Injection Brake voltage and time.
See Section 13.5 on pages 29 and 30.
• Slip Compensation (COMP) – Maintains set motor speed under varying loads. See Section 13.6
on page 30.
• Current Limit (CL) – Sets the current limit (overload) which limits the maximum current to the
motor. See Section 13.7 on pages 30 and 31.
• Boost (BOOST) – Sets the amount of Boost which can be used to obtain maximum low speed
performance. See Section 13.8 on pages 31 and 32.
• Jog (JOG) – Sets the “jog” speed of the motor. Must be used with the optional Run-Stop-Jog
Switch Kit (See Table 2 on page 9). See Section 13.9 on page 32.
