Process sequence and signal states

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].

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.

Dynamics parameters are applied (also during ongoing movement)

PO 2

Maximum speed

[2] – [4]

Start/stop of the axis

PO 1:7

  • "1": Acceleration to the setpoint torque specified by process data word PO 10, taking into account the maximum speed from process data word PO 2. The acceleration is determined by the setpoint torque and the applied load torque.
  • "0": The maximum speed is internally set to 0. Thus, the setpoint torque becomes 0. The deceleration is determined by the applied load torque.
  • After stopping, no torque is applied to the drive. The behavior at idle state depends only on the applied load torque.

[3] – [4]

[5] – [6]

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

PI 1:11

[4] – [5]

Setpoint torque inversion

 

The drive decelerates and reverses according to the sign of the torque input. The deceleration and acceleration are determined by the setpoint torque and the applied load torque.
