  • Page 105: Appendix 6 Dynamic Braking Option

    The GPD 315 has an integral braking resistor. However, to make use of the Dynamic Braking function requires addition of either a Braking Resistor (for 3% duty cycle) or Braking Resistor Unit (for 10% duty cycle).
  • Page 106 1. Mount the Braking Resistor, along with an overload or thermostat, in a suitable metal enclosure. 2. At the GPD 315. Connect the leads from the Braking Resistor to drive terminals B1 and B2, and make connections to external control circuit, as shown in Figure A6-1.
