Encoder dimensioning: Calculate maximum number of increments per revoluon of the encoder
Max. encoder increments = f

[rpm]
Max. encoder increment = 100000 [Hz] * 60 s / 1500 [rpm] = 4000 Increments/revoluon
f

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 >= 512 increments [1]" in 0x2630:002 (P410.02) to cong-
ure the digital inputs DI3 and DI4 as encoder inputs.
2.
Set the encoder number of increments per revoluon in 0x2C42:001 (P341.01) according
to the manufacturer data/encoder data sheet.
