DSCDP Hardware Manual 37
Example of a power stage relay and short-circuit relay used with an emergency stop push button:
Remark: If the motor's short-circuit relay is not powered (motor's phases shorted) and if the user performs
a 'PWR ON' on the controller, the 'hardware overcurr' error will occur (which must be avoid). If this
relay is not powered while the controller is in 'PWR ON', the same error will occur. To avoid this
problem, the DIN1+ can be used as described in the above-mentioned diagram. Refer to the
corresponding 'Operation & Software Manual' for more information about the use of DIN1+ (K33
parameter).
3.5.4 Connector JC14: Housed format, brake resistor
This connector is only present on the DSCDPxx4-xxx format.
Warning: High power may be present on this connector, depending on the application.
Caution: Use only resistor with thermal shutdown protection. The resistor minimal value is 40Ω. The use
of an undersized power and energy withstand capability resistor could generate an explosion.
If you determine that a regeneration resistor is necessary, select it to fit your application (refer to the 'Braking
resistor' technical note to calculate the value of this resistor). This resistor must include a thermal switch.
Example of resistor used by ETEL: Frizlen GmbH (Germany), cemented, double pipe resistor, type
FZZCQU-400x65, 39 Ω, 1200 W at 300°C. Metallic case protection (shielding), shielded connector.
Remark: The tightening torque for the screws of the brake resistor connector is 0.6 Nm max.
3.6 Optional boards connector
3.6.1 Connector JC8: Depends on the type of board
Phoenix Contact PC 4/2-G-7.62 (plastic connector)
