Status and control signals

The operation state of the drive system will be commanded and acknowledged by means of control and status signal.

The optional EF logic (power output stage enable) has to be controlled by binary inputs and outputs. Any other signals and states can controlled and read by binary inputs and / or fieldbus.

Status signals

Signal

 Name

Meaning
SBM 'System ready message'

After system booting without an error, SBM will be set and shows that the system is free of error.

In case of an error SBM will be reset and a diagnosis message will be generated. The system reaction in case of an error (e.g. running out, brake down according ID32873 'Deceleration ramp RF inactive', system booting abort) depends on the kind of error. (See document Diagnostic messages (Part no. 25786), chapter Meaning of the diagnostic messages.

The diagnosis messages can be read out with the software AIPEX PRO or read and evaluated by a controller. After the error cause is removed a system booting (ID33730 'System booting') has to be executed.

QUE

 'Acknowledgement DC bus on'

QUE acknowledges that the DC bus voltage is inside the valid range.

QRF

 'Acknowledgement controller enable'

QRF acknowledges the active control mode of the drive. Setpoints can be set depending on the configured operation mode (ID32800...). If QRF = 0 the drive is free of torque and no control mode is active.

Control signals

Signal

Name

Meaning

FL

 'Clear error'

FL causes a system booting after the reason for an error message is remedied and the drive is still in error state SBM = 0). The sucessfully finished system booting is acknowledged with the SBM = 1 signal. Clear error can only be executed if RF = QRF = 0 by a pulse signal ≥1 ms on the binary input or via fieldbus interface.

Clear error can be executed as follow:

  • Configuration FL to an binary input
  • ID99 'Diagnosis reset status class 1'
  • ID32913 'Clear error'

UE

 'DC bus on'

UE activates (signal-edge controlled) the loading procedure of the DC bus capacitors in the power supply device. UE can only be executed if SBM = 1. A successfully finish of the charging procedure is acknowledged by QUE = 1. If UE is reset, the capacitors will be discharged, QUE will be reset.

Between 2 consecutive UE on signals, a device specific inhibit time has to be considered. See document Servo drives KE/KW (Part no. 28932), chapter Product planning, subtopic Inhibit Time for Control Signal UE.

RF

 'Controller enable'

RF (signal-edge controlled) causes a system booting if at least one parameter has been changed before. RF activates the motor control in the current operation mode (e.g ID32800 'AMK main operating mode'. The motor is energized, setpoints are processed and the acknowledgement signal QRF will be set. RF can only be activated if SBM = QUE = 1. If RF is set, the power output stage are active. For devices with the option 'external power output stage enable' additionally EF/FE2 = 1 must be set. If the prerequisites are not fulfilled, the device generates an error message and resets SBM if someone try to set RF.

IF RF is withdrawal during operation the motor is ramped down according ID32782 'Deceleration ramp RF inactive' until standstill (≤ 6 RPM) and unenergized. QRF will be reset.

If a motor holding brake is active the signals RF and QRF on/off will be delayed device internal, depending on parameter ID206 'Drive on delay time' and ID207 'Drive off delay time'.
optional:
EF/EF2 'Power output stage enable'

Interrupting the control inputs EF/EF2 will cause the trigger signals for control of the power output stages to be safely blocked in two channels. The motor is in a secure state torque off protected against restart. This safety function is certificated according to EN ISO 13849-1:2008 (Cat.4, PL e) and EN 954-1: 1996, cat. 4.

See document Device description Servo drives KE/KW (Part no. 28932), chapter Function description KW, Function description - EF safety function.
