two types of terminals: terminals with 1.6 kΩ (1/2 W) limit resistance and termi-
nals with no resistance. Select the terminals in accordance with the power
requirements and the specifications of the motor drive to be used.
Connect a load of 7 to 30 mA (or 7 to 16 mA for terminals with 1.6-kΩ limit resis-
tance) to the output section. If a current greater than this is used, it will cause
damage to the PCU's internal components. Also, be sure to use the CW/CCW
output method when using pulse output terminals with limit resistance.
