CN4 - Digital Inputs / Outputs

The connection CN4 provides several digital inputs and outputs on the drive:

  • The digital inputs A_DI1 / A_DI2 (Single Drive) or A_DI1, A_DI2 / B_DI1, B_DI2 (Double Drive) can be configured as digital inputs or as Touchprobe inputs via the EcoStruxure Machine Expert Logic Builder.

  • The digital inputs A_DI5 /A_DI6 (Single Drive) or A_DI5, A_DI6 / B_DI5, B_DI6 can be configured as digital inputs or as digital outputs via the EcoStruxure Machine Expert Logic Builder.

  • The filter time constant of the digital inputs can be set to 1 ms or 5 ms.

  • The filter time constant of the Touchprobe inputs is fixed at 100 µs.

NOTE: For the digital inputs/outputs, if the 24 V supply is interconnected to any additional devices via the connection CN5, the maximum current carrying capacity must be respected:

  • Continuous current carrying capacity of the plug-in connectors: 3 A

  • Maximum current carrying capacity of the plug-in connectors: 4 A, 1 s

The number of the devices that can be connected depends on the application.

CN6 - Inverter Enable 1–Channel

The Inverter Enable signal supplies the gate driver with voltage. In this way, the STO (Safe Torque Off) requirements according to EN 61508 and ISO 13849-1 are met. IEA1 is internally connected with IEA2 electrically, and IEB1 is internally connected with IEB2 electrically.

The single channel Inverter Enable is valid only for Lexium 62 variants C/D/G, refer to Extended Safety-Related Functions - Inverter Enable via Hardware Input.

 DANGER
INADEQUATE SAFETY FUNCTION
Do not use 1-channel Inverter Enable wiring with Lexium 62 variants E/F.
Failure to follow these instructions will result in death or serious injury.
