ABB NextMove e100 User Manual

4-12 Input / Output MN1941WEN
4.3.2 Digital outputs and relay
The digital outputs are available on connectors X4 and X11, as shown in section 4.1.1.
A digital output can be configured in Mint as a general purpose output or a global error
output. Using a digital output to enable a remote drive is not recommended; see section
4.3.1.2 on page 4-7. Outputs can be controlled directly from Mint WorkBench, or by the Mint
OUT and OUTX keywords. Outputs can be shared between axes and can be configured using
Mint WorkBench (or the OUTPUTACTIVELEVEL keyword) to determine their active level.
4.3.2.1 DOUT0 - DOUT7
An external supply (typically 24 V DC) is used to power the UDN2982 output devices, as
shown in Figure 15. When an output is activated, current is sourced from the user supply
through a UDN2982 output driver.
 A total of 500 mA may be sourced by DOUT0 - DOUT7, providing an average 62.5 mA
per output when all outputs are on (100% duty cycle, 24 V supply). If the total current
exceeds 1 A a self-resetting fuse will operate, which may take a few minutes to reset.
 An individual output can provide a maximum continuous current of 350 mA, but if other
outputs are being used the total current must not exceed 500 mA.
 The maximum allowable power dissipation for the UDN2982 driver is 1.5 W.
If an output is used to drive an inductive load such as a relay, a suitably rated diode must be
fitted across the relay coil, observing the correct polarity. The use of shielded cable is
recommended.

4.3.2.2 DOUT8 - DOUT11
DOUT8 - DOUT11 use the same type of output circuitry as DOUT0 - DOUT7, with their own
UDN2982 output driver. Because only four of the UDN2982’s eight outputs are being used,
the average current available on DOUT8 - DOUT11 is increased:
 A total of 500 mA may be sourced by DOUT8 - DOUT11, providing an average 125 mA
per output when all outputs are on (100% duty cycle, 24 V supply). If the total current
exceeds 1 A a self-resetting fuse will operate, which may take a few minutes to reset.
 An individual output can provide a maximum continuous current of 350 mA, but if other
outputs are being used the total current must not exceed 500 mA.
 The maximum allowable power dissipation for the UDN2982 driver is 1.5 W.
