DOK-RCON03-EFC-3600***-IT01-EN-P
Rexroth Frequency Converter EFC 3600
Minimum unit 0.01 Hz
Factory default 50.00 Hz
When "The first frequency setting source" [b1.00]=1, the value of [b1.04] is the set fre‐
quency.
b1.05 Max. frequency
Setting range 50.00 ~ 400.00 Hz
Minimum unit 0.01 Hz
Factory default 50.00 Hz
b1.06 Upper frequency
Setting range [b1.07] ~ [b1.05]
Minimum unit 0.01 Hz
Factory default 50.00 Hz
b1.07 Lower frequency
Setting range 0.00 ~ [b1.06]
Minimum unit 0.01 Hz
Factory default 0.00 Hz
● [b1.05] is the maximum allowed output frequency of the frequency converter.
● The "Upper frequency" [b1.06] and "Lower frequency" [b1.07] represent the maxi‐
mum and minimum allowed output frequency set according to the requirements in
applications.
b1.08 Lower frequency mode
Setting range 0 ~ 1
Minimum unit 1
Factory default 0
b1.09 Hysteresis frequency width
Setting range 0.00 ~ [b1.07]
Minimum unit 0.01
Factory default 0.00
Two running modes are available when the lowest frequency is reached:
● [b1.08]=0: Running with 0 Hz
When the lower frequency is reached, the frequency converter is running with 0 Hz.
To avoid the tingle at lower frequency, a hysteresis frequency width is needed.
● [b1.08]=1: Run with lower frequency
If the lower frequency is reached, the frequency converter is running with the lower
frequency. If command frequency is higher than [b1.07]+[b1.09] again, the output
