There are two different types of DSCDP housed formats: the DSCDPx24-xxx and the DSC2Px34-xxx.
All the specifications are given for an ambient temperature ranging from +15°C (59°F) to +30°C (86°F):
Remark: The values given in the following table are valid for each motor.
(1): With optional board mounted on the DSCDP, no external device connected to the I/O. The current can
change depending on the type(s) of encoder(s) used. A current equal to about twice the above-mentioned
value can be necessary to switch on the controller (because of the trigger pulse).
Remark: With PWM at 18 kHz, the current ripple in the motor is at 36 kHz.
With two-phase motor, the current in 'motor phase 1- / 2-' (pin 3 of JC7 and JC11 connectors) is
equal to (√2 x motor phase 1+) or (√2 x motor phase 2+). Be careful to use the suitable cable
diameter.
For an ambient temperature exceeding +30°C, a derating of 0.3 A per degree must be applied on
the above-mentioned current values
The values given in the above-mentioned table are given for a sinusoidal output current with a
frequency higher than 0.5 Hz. The losses induced by a AC current are shared between the
transistors. A DC current heat up only some of the IGBTs and can induce their breakdown after
10 minutes if the current is near the maximum full load.
