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.
