PAM-199-P-PFN
2 Characteristics
This module is used for the control of a directional valve with two solenoids or up to two (pressure or throttle)
valves with one solenoid. With the parameter FUNCTION the operation mode can be switched. Various ad-
justable parameters allow for an optimized adaptation to the respective valve. The integrated power amplifier
is an inexpensive and space-saving solution.
Controlling the amplifier is realized here via a ProfinetIO interface. Furthermore this provides changing most of
the parameters via the bus.
The output current is closed loop controlled and therefore independent from the power supply and the solenoid
resistance. The output stage is monitored for cable breakdown, is short circuit proof and disables the power
stage in case of an error.
RAMP, MIN and MAX, the DITHER (frequency and amplitude) and the PWM frequency are programmable.
In addition, the valve characteristics can be linearized via 10 XY-points. For example: using pressure valves a
linear behavior between input signal and pressure can be reached.
Typical applications
: Control of directional, throttle and pressure valves, which need a flexible adaptation of
the solenoid control. All typical proportional valves of the different manufactures (BOSCH, REXROTH,
PARKER, EATON ...) can be controlled.
