_ENCD – Encoder
331-ECLNC - Lines per revolution of encoder
Source: Encoder Line Count
Function: Lines per revolution of the encoder (only for optical encoders Gx). Encoders with 512 to
4096 in increments of 2 can be used.
334-ECNPP - Number of pole pairs of encoder
Source: Encoder Number of Pole Pairs
Function: Number of pole pairs of the encoder (only for resolvers Rx)
AS = Asynchronous machine
PS = Permanent magnet excited synchronous machine
Values:
Minimum Maximum Factory set. Unit MODE SMARTCARD Type
512 4096 2048 – R4W4 DRIVE USIGN16

11R1AS, PS
22R2 AS
33R8 PS
4 4 – (only MC7000)
Note:
With higher-pole resolvers (e.g. R8) a higher resolution is obtained and so smoother
operation, but also several zero pulses per revolution.
Note:
The number of pole pairs of resolver ECNPP must be equal to that of the motor
(MONPP) or equal to one or a whole-number multiple of the number of pole pairs of
the motor.
