GENERAL.
Dynamic braking (DB) enables the motor to be brought to a smooth and rapid stop.
This is achieved by dissipating the regenerative energy of the AC motor across the resistive
components of the Dynamic Braking option. For further details on dynamic braking, see the option
instruction sheet shipped with the dynamic braking components.
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). See table below. In either case, interface to external control circuitry is
necessary to ensure that dynamic brake resistor overheating is communicated to the drive as a
fault condition.
