INFORMATION

For the behavior of the drive at idle state, observe the information in the "Stop functions" section in the parameterization of the inverter under [Functions] > [Monitoring functions] > [Control functions].

Description

0

Enable/emergency stop

PO 1.0

  • "1": Enable
  • "0": Stop with FCB 14 Emergency stop drive function.

1

Enable/application stop

PO 1.1

  • "1": Enable
  • "0": Stop with FCB 13 Stop at application limits drive function

2

Reserved

PO 1.2

 

3

Release brake

(without enable)

PO 1.3

If necessary, the function can be activated via the parameter "Release brake/deactivate DynaStop® with FCB 01 – enable" (index 8501.2).

For decentralized devices, also check the position of the DIP switches.

4

Jog positive

PO 1.4

Signal for moving the drive in positive direction in jog mode

5

Jog negative

PO 1.5

Signal for moving the drive in negative direction in jog mode

6

Reserved

PO 1.6

 

7

Start/stop with fieldbus ramp

PO 1.7

  • "1": Start
  • Movement enabled in all operating modes except for jog mode.
  • In referencing mode, the start signal is needed also for referencing without reference travel.
  • "0": Behavior depending on the operating mode used
    • In referencing mode/torque control: Stop with FCB 02 Stop standard drive function, with the deceleration specified by process data word PO 4.
    • In the other operating modes: Deceleration with the value of process data word PO 4 to speed 0.
    • Behavior in idle state:
    • The motor is held at speed 0 subject to speed control or position control depending on the operating mode. For motors without encoder, the stop by setpoint function must be used.
    • If the drive is stopped with the FCB 02 Stop standard drive function, the drive behaves according to the behavior at idle state set under [Monitoring functions] > [Control functions] (index 8563.1 or 8564.1).

 

 

 

 

8

Error reset

PO 1.8

Reset of the error with the positive edge of the signal.

9

Reserved

PO 1.9

 

10

Activate drive train 2

PO 1.10

  • "0": Drive train 1 is active
  • "1": Drive train 2 is active
  • Drive train 2 is only available for single-axis modules. For instance, it can be used to configure an emergency mode without encoder feedback.

11

Reserved

PO 1.11

 

12

Deactivate SW limit switches

PO 1.12

The signal is only evaluated if software limit switches are configured and activated.

  • "0": Monitoring of software limit switches enabled.
  • "1": Monitoring of software limit switches disabled.

13

Activate output stage inhibit

PO 1.13

  • "1": Output stage inhibit activated
  • The brake is applied. If no brake is installed, the motor coasts to a stop.
  • "0": Output stage inhibit not activated.
  • The output stage can be enabled.

14

Activate standby mode

PO 1.14

Standby mode can only be activated when the output stage is inhibited.

  • "1": Standby mode activated.
  • "0": Standby mode not activated.

15

MOVIKIT®

Handshake In

PO 1.15

The signal is copied internally to status word bit 15 (MOVIKIT® Handshake Out). If the Handshake Out signal remains constant with changing Handshake In signal, the copying operation has failed and the device-internal processing of the MOVIKIT® software module is disrupted.
