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 the 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 safety option (see Functional Safety see "Functional Safety").

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 (see Online Help).

Digital-In 1 and 2

These inputs (IECClosed"International Electrotechnical Commission" IEC is a not-for-profit, non-governmental international standards organization that prepares and publishes International Standards for all electrical, electronic and related technologies 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: 11 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 the setup software.

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. For more information refer to WorkBench.

Technical characteristics

  • Floating, reference common line is DGND
  • High: 11 to 30 V/2 to 15 mA , Low: -5 to +5 V/<15 mA
  • Update rate: firmware reads hardware input state every 250 µs

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 if configured as input

  • RS485, reference common line is AGND
  • No wire break detection
  • Digital IN/OUT 1/2: Selectable DC termination for differential or single ended input
  • Update rate: firmware reads hardware input state every 250 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 24V signal level! Will be damaged if connected to +24V!

Technical characteristics if configured as input

  • RS485, reference common line is 0V
  • No wire break detection
  • Digital IN/OUT 3/4: Selectable DC termination for differential or single ended input
  • Digital IN/OUT 5/6: AC termination for single ended input
  • Update rate: firmware reads hardware input state every 250 µs
