Inquire About This Product
basic information
The PMA20WF is a DC servo driver that enables speed control without a tachogenerator by incorporating an encoder input F/V converter, achieving low cost while pursuing servo performance. The power supply is designed for a single DC 24V battery power source. The power supply voltage range is DC 20V to 40V. The control loop is for speed and torque (current).
