Features
– Use as
closed-loop control electronics
for closed control
loops with PIDT1 controller and optional state feedback
– Substitutional closed-loop control (e.g. position control with
superimposed pressure/force control) possible
– Use as
command value electronics
for generating, linking
and standardizing signals
– Input for digital position measurement systems (2 x SSI or
1 x incremental)
– 6 analog inputs, voltage (±10 V, 0…10 V) and current
(4…20 mA) selectable via software, input resistance
of AI1 > 10 MΩ
– 3 analog outputs, 1x selectable voltage (±10 V, 0…10 V) or
current (0…20 mA, 4…20 mA), 2x voltage (±10 V)
– Numerous possibilities of signal linking and switch-over
– Release input and OK output
– 8 digital inputs
– 7 digital outputs, configurable
– Parameterizable ramp function
– 32 blocks with command values, velocities and controller
parameters
– Adjustment to hydraulic drive by means of area adjustment,
characteristic curve correction, overlap compensation,
residual velocity logic and zero point correction
– +10 V reference voltage output
– Serial interface RS232
– Up to 32 electronics can be interconnected for parameter-
ization and diagnosis via the local bus
