Motor and braking resistor
Driver allows connection of DC motors and braking resistor. Resistor is used to dissipate energy returned by
motor as a result of change of rotational velocity. Driver is equipped with internal braking resistor with 10 Ω
resistance and 10 W efficiency. In case of using a drive with high inertia it is possible to connect external
resistance. For this aim is used LOAD (5) output, second end should be connected to driver supply VDC+ (1).
Motor should be connected to M+(3) and M-(4)inputs, motor polarity can be important while use of drive with
encoder.
Picture. 5. Motor connection diagram and additional braking resistor (as an option)
CAUTION!
After connection of external braking resistor please properly set power and resistance of resistor and
driver power supply at SID116 – PC application. Lack of settings or entering wrong settings can cause
damage of a drive.
It is recommended to use a ferrite bead on motor cables to eliminate noises from commutator.
In case of drive with encoder its connection polarity force counting direction of encoder pulses.
