2.1.3 Ratings
To meet the specifications listed below, it is recommended to use an ETEL power supply (DSO-PWS). There
are two different types of 10F wide rack formats (the DSCDPx21-xxx and the DSCDPx31-xxx) and one type of
14F wide rack format (the DSCDPx32-xxx).
All the specifications are given for an ambient temperature ranging from +15°C (59°F) to +40°C (104°F)
and with an air flow of 2 m/s (400 LFM) inside the rack case:
Remark: The values given in the following table are valid for each motor.
(1)
: Continuous current can be reached only with forced air cooling (external fan necessary: refer to §2.1.4).
(2)
: 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.
Note: for DSCDPxxx-x2x, the DC current is equal to 450 mA at 48 VDC.
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.
