Commissioning; Parameterization - Bosch Rexroth RA 10 Series Instruction Manual

8 Commissioning

During all work for commissioning the analog amplifier, observe the general safety
instructions and intended use detailed in chapter 2 "Safety instructions" from
page 8 on.
▶ When commissioning the analog amplifier, the machine may pose unforeseen
hazards. Before commissioning the system, you must therefore ensure that the
vehicle and the hydraulic system are in a safe condition.
▶ The analog amplifier is commissioned by setting the potentiometers.
▶ Commission the machine and check the correct functioning of the analog
amplifier.
8�1 Parameterization
Risk of personal injury and damage to equipment�
Since the parameterization is completed when the electrical system is switched
on, the machine/vehicle can unintentionally move on and cause damage.
▶ Make sure that nobody is in the danger zone.
▶ Make sure that the machine/vehicle cannot start moving, if possible
(e.g. by disconnecting the gearbox or jacking the vehicle.
The analog amplifier must be set before commissioning so that at 100% of the
command value signal, it supplies the desired command value current at its output.
To set the analog amplifier, proceed as follows:
1� Turn the setting potentiometer at the RA for I
2� Set the setpoint potentiometer or the joystick, the sensor or the corresponding
signal source (in the following only referred to as setpoint potentiometer) to
100% (maximum value).
3� Turn the setting potentiometer for I
the valve or the drive just respond.
4� Turn the setting potentiometer I
hydraulic function is reached.
The setting potentiometer I
reaction (quantity/speed/pressure, etc.) has been reached, as otherwise
unnecessarily high current flows. Apart from that, the drive is not directly
reduced when the setpoint potentiometer is reduced (<100%). is reduced.
Vice versa, the maximum modulation is already achieved before 100% command
value presetting.
The correct setting exists if the drive directly follows when the setpoint
potentiometer is reduced from 100%.
