4.5. Current Settings
The proper current setting for each motor is shown on the individual
torque vs. speed curve. Use this current level to obtain the torque
shown. The access hole for the switches that set the motor current level
is located on the back of the unit (see next figure). Switches 1 through 6
are used to select the current level. Select the desired operating current
by setting the appropriate switch to position 1 (ON). The OFF position
is labeled "0." Only one switch should be ON. If two or more switches
are ON, the one selecting the highest current level is the active switch.
The switch settings are:
