Configurable I/O Application Functions

AO and AO1 analog output application functions

The analogue outputs AO and AO1 are the output currents of AOL (mA) and AOH (mA),

• AOL and AOH being configurable from 0 to 20 mA.

Examples AOL - AOH : 0 - 20 mA 4 - 20 mA 20 - 4 mA

Motor current (Code OCR) : the image of the motor rms current.

•AOH corresponds to twice the nominal speed controller current.

•AOL corresponds to zero current.

Motor frequency (Code OFR) : the motor frequency estimated by the speed controller.

•AOH corresponds to the maximum frequency (parameter tFr).

•AOL corresponds to zero frequency.

Ramp output (Code ORP) : the image of the ramp output frequency.

•AOH corresponds to the maximum frequency (parameter tFr).

•AOL corresponds to zero frequency.

Motor torque (Code TRQ) : the image of the motor torque as an absolute value.

•AOH corresponds to twice the nominal motor torque.

•AOL corresponds to zero torque.

Signed motor torque (Code STQ) : the image of the motor torque and direction :

•AOL corresponds to a braking torque = twice the nominal torque

•AOH corresponds to a motor torque = twice the nominal torque.

•AOH + AOL corresponds to zero torque.

2

Signed ramp (Code ORS): the image of the ramp output frequency and direction.

•AOL corresponds to the maximum frequency (parameter tFr) in the reverse direction.

•AOH corresponds to the maximum frequency (parameter tFr) in the forward direction.

•AOH + AOL corresponds to zero frequency.

2

PI setpoint (Code OPS): the image of the PI regulator setpoint

•AOL corresponds to the minimum setpoint.

•AOH corresponds to the maximum setpoint.

PI feedback (Code OPF): the image of the PI regulator feedback

•AOL corresponds to the minimum feedback.

•AOH corresponds to the maximum feedback.

PI error (Code OPE) : the image of the PI regulator error as a % of the sensor range (maximum feedback

– minimum feedback)

•AOL corresponds to the maximum error < 0

•AOH corresponds to the maximum error >0

• AOH + AOL corresponds to null error (OPE = 0) 2
