Rexroth Frequency Converter EFC 3600
Setting range [E0.25] ~ 100.0 %
Minimum unit 0.1 %
Factory default 100.0 %
E0.28 Frequency corresponding to curve 2 max. reference
Setting range 0.00 ~ [b1.06]

The frequency converter actually has two external analog inputs, AIV voltage signal (0
~ 10 V) and AIC current signal (4 ~ 20 mA). When AIV or AIC input is used as the refer‐
ence frequency channel, the relation between the reference channel and the set fre‐
quency is illustrated as below:
Fig.8-31: Relationship between reference channel and set frequency
● The relationship between "the reference frequency after gain and filter processing"
with "the set frequency commands" is determined by [E0.21] ~ [E0.28] and [E0.20].
● AIC and AIV can use both curve 1 and curve 2.
● [E0.21] ~ [E0.24] are used to define characteristics of curve 1. See figure below:
Fig.8-32: Characteristics curve 1
● [E0.25] ~ [E0.28] are used to define characteristics of curve 2. See figure below:
