Resolver settings

Resolvers with a number of pole pairs > 1 are not absolute value encoders.
Bit 4 in (Lenze status word 2) therefore remains set to "0".
The "distinguishable revolutions" specification in
The following applies to synchronous motors:
When the number of motor pole pairs to the number of resolver pole pairs is an integer

ratio (0x2C01:001), the pole position only has to be identified once.
When the number of motor pole pairs to the number of resolver pole pairs is a non-inte-
•
ger ratio (0x2C01:001), the pole position must be identified every time the inverter is con-
nected to 24 V.4Synchronous motor: Pole position identification (PPI)

Info
Is set by the firmware according to the available version:
• 0: no absolute value encoder (sin/cos encoder) or resolver with num-
ber of pole pairs > 1
• 1: Single-turn absolute value encoder or resolver with number of pole
pairs = 1
• >1: Multi-turn absolute value encoder
The sensitivity can be reduced by percentage, e. g. in case of EMC inter-
ferences.
Setting the number of bits to be used for resolving a mechanical motor
revolution.
Resolving the position detection by the motor encoder.
Setting of the number of motor revolutions.
Only setting "1" is accepted.
Setting of the encoder increments per second.
Setting of the motor revolutions per second.
0x2C46 is also set to "0".
