Master Communication
Features
The analog interface is an interface for master communication with
analog command values and digital I/Os (drive enable, Drive Halt...) with
the following features:
• analog inputs (12 bit) to be assigned to parameters, with offset and
scaling to be set (number depending on control section design)
• sampling rates for the analog inputs:
• channel A: position loop clock T
(Advanced: T = 250 µs; Basic: T = 500 µs)
• channel B: T = 2 ms
• assignment of analog inputs to two drive parameters (command
values) is possible
• freely configurable incremental encoder and SSI emulation of the
different position values in the drive (actual position value, position
command value...) load- or motor-related via position scaling
(S-0-0076)
• absolute encoder emulation:
• reference to be set via P-0-0012, C0300 Command Set absolute
measuring
• resolution to be set, only binary resolution (incr./motor rev. or mm)
• power failure bit available
• incremental encoder emulation:
• emulation of the reference pulse
• reference pulse to be set; dead time compensation
• resolution to be set (incr./motor rev. or mm)
• maximum frequency monitoring
• digital control and status information determined via configuration of
the digital inputs of the control section:
• digital control inputs for analog master communication:
• signals "drive enable" and "Drive Halt"
• zero switch, limit switch (+/-); clearing errors and E-Stop
• digital status outputs for analog master communication:
• ready and warning output
• relay output for readiness for operation
Note: For the BASIC ANALOG control section the analog inputs and
the hardware for encoder emulation have already been
integrated on the control section. The ADVANCED and
BASIC UNIVERSAL control sections require optional add-on
cards for analog I/Os (MA1) and encoder emulation (MEM).
