Digital I/O – X21
The servo drive provides 4 digital inputs and 2 digital outputs on the X21 DB9 (9-pin D-sub) port.
All inputs and outputs can be used to initiate pre-programmed actions. A list of actions is included in WorkBench. If an input, or output is programmed, it must be saved to the servo drive.

Maximum distance for unshielded I/O lines is 3m inside the cabinet. Ensure EMC shielding if the I/O cable leaves the cabinet. |

Depending on the selected function, the inputs are high or low active. Set the digital input filter in WorkBench to change sensitivity of the inputs |
Type 1 digital inputs according to IEC61131-2 have the following input voltage current characteristics:
| Channel | Type | Explanation |
|---|---|---|
|
DIN1, DIN2 |
Fast, 24V, |
An isolated, current sinking digital input referred to GND_24V. The threshold and current characteristics are IEC61131-2 Type 1. The activation delay (0->1) is <1μs and the de-activation delay (1->0) is <1μs. Additional filtering also takes place in the FPGA with selectable filter values. Can also support quadrature feedback. |
|
DIN3, DIN4 |
Slow, 24V, 61131-2 |
An isolated, current sinking digital input referred to GND_24V. The threshold and current characteristics are IEC61131-2 Type 1. The activation delay (0->1) is on the order of 5μs and the de-activation delay (1- >0) is on the order of 500μs. Additional filtering also takes place in the FPGA with selectable filter values. |
|
DOUT1, DOUT2 |
Slow, 24V, |
An isolated pair of volt-free contacts. Collector (+) and emitter (-) brought out to separate pins. 100mA rated with latch off upon over-current. |
