Maximum encoder speed (in this example: 1500 rpm)
Max. encoder increments Maximum number of increments per encoder revoluon
Select an encoder with a maximum number of increments per revoluon which
is lower than or equal to the calculated number. The higher the number of
increments per revoluon, the more stable the system is.
Basic steps for conguring the encoder in the »EASY Starter«:
1.
Set the selecon "HTL encoder (AB) [1]" in 0x2630:002 (P410.02) to congure the digital
inputs DI3 and DI4 as encoder inputs.
2.
Set the encoder increment in 0x2C42:001 (P341.01) according to the manufacturer data/
encoder data sheet.

Sengs for digital inputs: Input funcon
(DI sengs: Input funcon)
Input funcon of the digital terminals DI3 and DI4.
0 Digital input DI3 = digital input
DI4 = digital input
1 HTL encoder (AB) (from version 02.00) DI3 = HTL input for encoder track B
DI4 = HTL input for encoder track A
2 Pulse train (from version 03.00) DI3 = digital input
DI4 = HTL input for pulse train
3 Pulse train/direcon (from version 03.00) DI3 = HTL input for direcon specicaon; HIGH level = counter-clock-
wise (CCW)
DI4 = HTL input for pulse train
