11.14.5 Impacts of parameter changes on the signal PPI_bPolePositionAvailable

Changing the type of motor control (C00006)

Changing relevant motor data

Changing relevant encoder data

Initial situation 1 Parameter change Impact

• PPI_bPolePositionAvailable = TRUE

• Motor control (C00006

) = "1: SC:

Servo control sync. motor"

In C00006

another motor control is

set.

PPI_bPolePositionAvailable remains

on TRUE since the signal is irrelevant

for an asynchronous motor.

Initial situation 2 Parameter change Impact

• PPI_bPolePositionAvailable = TRUE

• Motor control (C00006

) =

• "2: SC: Servo control async.

motor" or

• "4: SLVC: Sensorless vector

control" or

• "6: VFCplus: V/f control" or

• "7: VFCplus: V/f control"

In C00006

, the motor control "1: SC:

Servo control sync. motor" is set.

PPI_bPolePositionAvailable is reset to

FALSE since the signal is relevant for a

synchronous motor and apparently a

new motor has been selected.

Initial situation Parameter change Impact

PPI_bPolePositionAvailable = TRUE One of the following parameters is

changed:

• Rated motor speed (C00087

)

• Rated motor frequency (C00089

)

• Rated motor voltage (C00090

)

PPI_bPolePositionAvailable is reset to

FALSE since it is assumed that the

connected motor has been changed.

Initial situation Parameter change Impact

PPI_bPolePositionAvailable = TRUE One of the following parameters is

changed:

• Resolver - number of pole pairs

(C00080

)

• Encoder - number of increments

(C00420

)

• Encoder type (C00422

)

• TTL encoder signal evaluation

(C00427

)

• Motor encoder selection (C00495

)

PPI_bPolePositionAvailable is reset to

FALSE.
