4.4.2 Digital outputs

The digital outputs are available across a range of pins, as shown in section 4.2.1.

H12 general purpose digital outputs.

HOne error output, configurable as a general purpose digital output.

HUpdate frequency: Immediate.

There are 12 general purpose digital outputs. An output can be configured in MintMT as a general purpose output, a drive enable output or a global error output. Outputs can be shared between axes and can be configured using WorkBench v5 (or the OUTPUTACTIVELEVEL keyword) to determine their active level.

4.4.2.1DOUT0 - DOUT7

Outputs DOUT0 - DOUT7 are driven by a ULN2803 device. The outputs are designed to sink current from an external supply (typically 24VDC), but have no overcurrent or short circuit protection. When an output is activated, it is grounded through the ULN2803.

The ULN2803 has a maximum power dissipation of 2W at 25°C. The total output requirements of DOUT0 - DOUT7 must not exceed this limit. The maximum current limit for an individual output is 500mA if only one output is in use, reducing to 150mA if all outputs are in use. These limits are for a 100% duty cycle.

If the outputs are driving inductive loads such as relays, connect the OUT COM connection to the output’s power supply, as shown in Figure 10. This will connect internal clamp diodes on all outputs.
