Encoder simulation
The encoder socket (X4) is used as an output for the encoder
simulation. Two TTL complementary signals (V

0,5V at I = 20mA) shifted by 90°C with 256, 512, 1024 or 2048
increments are generated per revolution (adjustable via C030). This
output is used for actual value feedback for closed-loop control
(positioning control) or as a set value for slaves (master/slave
operation). The current capacity is 20 mA per channel.

Resolver
2-pole resolvers (V=10V,f=5kHz) are fitted as standard. The Lenze
servo motors are already equiped with the corresponding resolvers.
The resolver is connected by means of a 9-pole socket (X3). The
resolver supply cable and the resolver are monitored for open
circuit (fault indication Sd2).
