DSC2P Hardware Manual

For the motor wiring, refer to the EN 60204/1 or NEC (UL) standard in order to use the
adequate cable section.
The DSC2P housed format already includes an in-built filter. An additional filter can be added
(for example (Schaffner FN2070-16-06) or a 'common mode choke' of 3mH (Schaffner
RD6127-16-3m0)) to reduce further electromagnetic disturbances.
For safety reasons, always connect first the protective earth (PE) to the screw under the DSC2P!
Remark:
The tightening torque for the screws of the power input connector is 0.6 Nm max.

Connector JC12: Housed format, auxiliary supply input
This connector is only present on the DSC2Pxx
4
-xxx controller.
For safety reasons, always connect first the protective earth (PE) to the screw under the DSC2P!
Remark:
The tightening torque for the screws of the auxiliary input connector is 0.25 Nm max.

The
power stage relay
(24 VDC / 2880
Ω
) allows the user to cut the +15 VDC voltage supplying the IGBT
gate driver, when the +24 VDC supply input of this relay is stopped.
If the power stage relay is not powered, the IGBT gate driver is deactivated (IGBT opened) and no power
is present on the motor's output. The power stage relay
must
then be powered (pin 4 to 0 V and pin 5 to
+24 VDC) to have power on the motor's output (otherwise an ’Inrush error’ will appear).
•
The
motor's
short-circuit relay
(+ 24 VDC / 490
Ω
), which is
optional
, allows the user to short-circuit the
motor's phases.
If this relay is not powered, the motor's phases are shorted. The motor's short-circuit relay
must
then be
powered (pin 1 to +24 VDC) to have power on the motor's output.
