Digital Inputs
The drive provides 8 digital inputs on X21. Dual axis drives and drives with built-in option IO or DX offer additional 4 inputs on X22 and 2 programmable Input/Outputs on X22. If X23 is built-in and not used for feedback or EEO function, then it offers 4 additional programmable Input/Outputs.
All inputs can be used to initiate pre-programmed actions. A list of actions is included in WorkBench. If an input is programmed, it must be saved to the drive.
The drive provides 4 safe digital inputs on X21 and X22. These inputs can be used as safe inputs, based on the installed functional option see "Technical Data"see "Safe Digital Inputs".

Maximum distance for unshielded I/O lines is 3 m inside the cabinet. If the I/O cable leaves the cabinet, it must be EMC shielded. |
|
Depending on the selected function, the inputs are high or low active. Digital input filter can be set in WorkBench to change sensitivity of the inputs. |
Digital-In 1 and 2
These inputs (IEC 61131-2 Type 1) are particularly fast and are therefore suitable for position latch functions. They can also be used as 24 V inputs for electronic gearing .
Technical characteristics
- Floating, reference common line is DGND
- High: 15 to 30 V/2 to 15 mA , Low: -5 to +5 V/<15 mA
- Update rate: firmware reads hardware input state every 250 µs
- High accuracy latch: motor feedback position or interpolated time is latched or captured within 2 µs of input signal transition (with digital input filter set to 40 ns)
- The AKD2G capture engine is polled every 62.5 µs (16 kHz) by the firmware
Wiring example
Digital-In 3 to 12
These inputs (IEC 61131-2 Type 1) are programmable with WorkBench.
Manufacturer setting:
- Digital-In 3: HW-Enable Axis 1
- Digital-In 4: HW-Enable Axis 2
- Digital-In 5 ...12: off
Choose the function you require in WorkBench and refer to the software for more information.

Wiring example
Digital-In/Out 1 and 2
Pins X22/A20-A21 (Digital-In/Out 1) and X22/B20-B21 (Digital-In/Out 2) can be defined as either inputs or outputs. For programming refer to WorkBench.

NOT compatible with 24V signal level! Will be damaged if connected to +24V! |
Technical characteristics when configured for input:
- RS485 common is AGND; not optically isolated
- No wire break detection
- Termination Selection: Unterminated or DC Terminated
- Differential or Single-ended
- For single-ended:- Negative terminal is open circuit; Positive input high signal = 3 - 5 V.
- Force input high with 5 V driver applied to DIO1/2+; pull input low by sinking DIO1/2+ to AGND.
Open circuit (floating) input will typically be high.
- Update rate: firmware reads hardware input state every 250 µs
- When used for capture, timing resolution is <1 µs
Wiring example
Digital-In/Out 3 to 6
X23 can be used for digital I/O. The channels can be defined as inputs or outputs. For programming refer to WorkBench.

NOT compatible with 24 V signal level! Will be damaged if connected to +24 V! |
Technical characteristics when configured for input:
- RS485 reference common line is 0 V
- No wire break detection
- DIO 3/4 Termination Selection: Unterminated (AC Termination) or DC Terminated
- DIO 5 Termination Selection: Unterminated (AC Termination) or DC Terminated on newer models*
- DIO 6 Termination Selection: Unterminated (AC Termination) Only
- Differential only
- Update rate: firmware reads hardware input state every 250 µs
- When used for capture, timing resolution is <1 µs
