Behaviour after mains ON
Behaviour after encoder error
Behaviour after resolver error
Initial situation 1
Behaviour after mains ON
• PPI_bPolePositionAvailable = TRUE
• Motor control (

motor"
• Resolver - number of pole pairs (
PPI_bPolePositionAvailable is only reset to FALSE if:
• Motor encoder selection (
) = "0: Resolver to
X7"
AND
• The number of motor pole pairs are (
integer multiple of the number of resolver pole pairs
(
).
Examples:
MSC motor
Motor - number of pole pairs = 4
Resolver - number of pole pairs = 1
The PPI_bPolePositionAvailable output is not reset to
FALSE.
Kuka motor
Motor - number of pole pairs = 4
Resolver - number of pole pairs = 4
Torque motor
Motor - number of pole pairs = 12
Resolver - number of pole pairs = 6
