Application notes

4.1. Input connection.

Connector

For the input connector (X10) a boxed header from Wurth is applied (612 008 217 21), a possible

mating wire connector is for example the 71600-608LF from FCI.

Wiring

For increasing the immunity of the PWM input signals the driver is equipped with differential inputs.

For reaching maximum performance the differential pairs should be physically kept close to each

other by using for example a flat cable with twisted differential pairs.

Although the differential concept already gives additional immunity it is still recommended to keep

the PWM signal lines away from conductors carrying large currents. Shielding of the wires will

increase the immunity further.

4.2. Input power.

The ramp-up of the supply voltage during start-up should be smooth and no dips should occur.

4.3. Disabling OCP

If it, for any reason, is desired to disable the OCP then this can be achieved by interconnecting:



X31 with X33 and



X22 with X23

Note that when X23 and/or X33 are not connected the driver will always enter its error stated when

PWM is applied.
