General
The amplifier modules are intended for assembly on top hat rails. The electrical connection is established via 3 tension spring plug-in connectors. The supply voltage is 24V DC.
Power supply unit [1]
The internal power supply unit has a making current limiter to prevent current peaks. Additionally, inverse-polarity protection is integrated.
Command value, command value summing device [3]
The “internal command value” comprises:
the “external command value”, connected at the input of the differential amplifier [2] the zero point offset [4]“Z/B” in the standard – setup adjustableFor pressure valves, a positive command value results in a pressure increase at the valve.
For valves 4W..., the following applies:
Via solenoid B, a command value of 0 ... +10 V or 12 ... 20 mA results in a flow in the valve from P to A and from B to T.
Via solenoid A, a command value of 0 ... -10 V or 12 ... 4 mA results in a flow in the valve from P to B and from A to T. In the expert set-up, inversion of the command value is possible [5] (see RE 30232-B).
In normal operation, the “internal command value” can be measured at the “v” measuring socket.
Ramps
A ramp limits the incline of the command value. You can choose between a single ramp [6] (one time for all ramps, default value) and a 4Q / 2Q ramp [7] (different times for the possible ramps). The 4Q / 2Q ramp times are set in the expert setup. The characteristic curve generator [9] does not influence the ramp time.
Command value attenuator “G” [8]
By means of the command value attenuator, the command value can be reduced.
Characteristic curve generator [9]
In the characteristic curve generator, the pre-set valve characteristic curve can be adjusted to the actual hydraulic and control-technical conditions.
The following can be adjusted in the expert setup:
Pilot current “B” Step “S” Maximum current “G” (with VT-MSPA2 separately possible for solenoid A and B)
Current controller [10]
The solenoid current is recorded, compared to the command value in the current controller and the difference is compensated.
Clock generator [11]
The clock generator creates the clock frequency "f" of the output stage. With Rexroth valves, the clock frequency sometimes changes dependent on the command value and/or the operating voltage.
Power output stage [12]
The current output stage creates the clocked solenoid current for the proportional valve. The solenoid current is limited to the maximum admissible current per output, depending on the set valve. The output stages are short-circuit-proof. With an internal interference signal or in case enable is missing, the output stage will be switched off.
Digital input [13]
The input DI can be set to four different functions:
1. Enable (factory setting) 2. VT-MSPA1 1) without function (permanent enable) 2. VT-MSPA2 command value inversion (permanent enable) 3. Ramp on/off (permanent enable) 4. Single or quadrant ramp (permanent enable)
Digital output [15]
Device notifies ready for operation if there is no cable break, no internal error and UB >=UBmin .

Product documentation for VT-MSPA..-2X:
Data sheet 30232 Operating instructions 30232-B CE declaration of conformity (available from Bosch Rexroth upon request) General information on the maintenance and commissioning of hydraulic components: Data sheet 07800 / 07900 Documentation on the Internet: www.boschrexroth.com/VT-MSPAx
Maintenance instructions:
The devices have been tested in the plant and are supplied with default settings. Only complete devices can be repaired. Repaired devices are returned with default settings. User-specific settings must be made by the machine end-user once again.
Notes:
In especially EMC-sensitive environments, additional measures must be taken (depending on the application, e.g. shielding, filtration) Wiring information Maximum possible spatial separation between signal and load lines. Do not lead signal lines through magnetic fields. If possible, install signal lines without intermediate terminals. Do not install signal lines in parallel to the load lines. Connect cable shields (see operating instructions 30232-B) For digital inputs and outputs as well as command and actual value, the max. admissible cable length for unshielded cables is 30 m. With longer cable lengths, shielded cables are to be used. The distance to radios must be sufficient (> 1m). With a strongly fluctuating operating voltage, it may in individual cases be necessary to use an external smoothing capacitor with a capacity of at least 2200 μF. Recommendation: Capacitor module VT 11110 (see data sheet 30750); sufficient for up to 3 amplifier modules. The upper and lower ventilation slots must not be concealed by adjacent devices in order to provide for sufficient cooling.Assignment switch position - valve type
