Signal states

[1]

General enable

  • PO 1:0 = "1"
  • Enable/emergency stop

PO 1:0

  • "1": Enable
  • "0": Deceleration with emergency stop ramp
  • PO 1:1 = "1"
  • Enable/application stop

PO 1:1

  • "1": Enable
  • "0": Deceleration according to application limit
  • PO 1:13 = "0"
  • Output stage inhibit (signal with highest priority)

PO 1:13

  • "0": Output stage enabled
  • "1": Output stage inhibited (the drive coasts to a stop or the brake is applied).

[1]

Activation of "relative positioning" application mode

PO 6

401 (decimal)

[2]

Feedback of the "relative positioning" application mode

PI 6

401 (decimal)

[3]

Dynamics parameters are applied (also during ongoing movement)

[3]

Start/stop with fieldbus ramp If the "Start" signal is revoked during movement to the first target, the drive is stopped and continues to move to the original target if this signal is set again.

PI 1:7

PO 2

PO 3

PO 4

  • "1": Drive accelerates with the corresponding table acceleration to approach the target position.
  • "0": Drive decelerates with the corresponding table deceleration and is held at speed "0" with position control.

[3]

Specification of the distance

(relative position)

PO 7

PO 8

"Target position" (high word)

"Target position" (low word)

[3] to [4]

and

[6] to [7]

Apply relative position

INFORMATION: The relative position is calculated once with the rising edge of the signal, and is saved. With the next positive edge (also during movement to the first target), the travel section can be extended or shortened by the specified relative position.

PO 1:6

  • "1": Apply relative position

Up to [3],

[5] to [6]

and from [8]

If the actual position lies within the configured window width, the feedback "In position" is issued. The drive stops subject to position control.

PI 1:7

  • "1": "In position" signal active

INFORMATION

If the motion sequence is interrupted by revoking the enable signals PO 1:0, PO 1:1 or PO 1:13, the movement must be restarted by setting "Apply relative position". The target position is calculated again and saved. The drive moves to another target position than originally requested. If the travel is not intended to be canceled, but merely interrupted (while maintaining the original target position), the drive can be stopped by removing the PO 1:7 "Start/stop" signal.
