VFD (Variable frequency drive)
Bosch Rexroth AB, Installation and maintenance manual, Hägglunds DOb, RE 15327-WA/05.2017
Behavior at low speed running
Code
Name
E0.15
Low speed running setting
For main pump electric motor the running frequency cannot be too low and hence
the frequency converter runs at 'Output frequency low limit' when the output
frequency is lower than [E0.10].
Direction Control
Code
Name
E0.17
Direction control
The actual direction is controlled by the configuration of parameter [E0.17]
'Direction control'.
0: Forward / Reverse
1: Forward only
2: Reverse only
3: Swap default direction
Acceleration/ Deceleration time configuration
Code
Name
E0.26
Acceleration time
E0.27
Deceleration time
Acceleration / deceleration time setting is the time for frequency increase from 0.00
Hz to [E0.08] 'Maximum output frequency' / the time for frequency decrease from
[E0.08] to 0.00 Hz respectively.
Stop mode setting
Code
Name
E0.50
Stop mode
0: Decelerating stop
The motor decelerates to stop according to the defined deceleration time.
1: Freewheeling stop
Once the stopping command is activated, the converter stops output and the motor
mechanically freewheels to stop.
2: Freewheeling with stop command, decelerating with direction change
• When stopping command is active, the motor freewheels to stop as [E0.50] = 1.
• When direction command is changed during running, the motor decelerates to stop
according to the defined deceleration time as [E0.50] = 0.
Setting range
0: Running at 0.00 Hz
1: running with low
