Process sequence and signal states

INFORMATION

For the behavior of the drive at standstill, observe the information in the section "Stop functions" in the "Control functions" configuration menu of the inverter.

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]

Dynamics parameters are accepted (also during ongoing movement)

PO 2

Maximum speed

[2] to [4]

Start/stop of the axis

PO 1:7

  • "1": The drive accelerates taking into account the maximum speed PO 2 with the setpoint torque specified via PO 10. The acceleration results from the setpoint torque and the application-dependent load torque.
  • "0": The maximum speed is internally set to 0, which means that the target torque becomes 0. The deceleration results from the applied load torque.
  • Standstill behavior: Torque is no longer applied to the drive so that the behavior depends on the load torque applied.

[1] to [2]

[3] to [4]

[5] to [6]

The final speed adjusts itself according to the setpoint torque and the load torque.

PI 1:11

[4] to [5]

Setpoint torque inversion

 

The drive decelerates and reverses according to the sign of the torque input. The deceleration or acceleration results from the setpoint torque and the applied load torque.
