Calibration
MM21X51C SERIES drives have six user adjutable trimpots: MIN
SPD, MAX SPD, IR COMP, TORQUE, DECEL, and ACCEL. Each
drive is factory calibrated to its maximum curent rating. Readjust
the calibration trimpot settings to accommodate lower current
motors.
All adjustments increase with clockwise (CW) rotation, and
decrease with counterclockwise (CCW) rotation. Use a non-metallic
screwdriver for calibration. Each trimpot is identified on the printed
circuit board.
Warning
Dangerous voltages exist on the drive when it is powered.
When possible, disconnect the voltage input from the drive
before adjusting the trimpots. If the trimpots must be
adjusted with power applied, use insulated tools and the
appropriate personal protection equipment. BE ALERT. High
voltages can cause serious or fatal injury.
