Process sequence and signal states

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

PO 1:1

  • "1": Release
  • "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

PO 3

PO 4

Setpoint speed (signed)

Setpoint acceleration

Setpoint deceleration

[2] – [4]

Start/stop with fieldbus ramp

PO 1:7

  • "1": Acceleration with the value of process data word PO 3 to the setpoint speed specified by process data word PO 2.
  • "0": Deceleration with the value of process data word PO 4.
  • After stopping, the motor is held at speed 0 subject to speed control. For motors without encoder, the stop by setpoint function must be used.

[3] – [4]

If the actual speed lies within the configured window width, the feedback "Setpoint/actual speed comparison" is issued.
