1.6.2.1.1 Intended Purpose
The encoder and PWM module CD522 can be used at the following devices:
● Communication interface modules (e. g. CI501-PNIO, CI541-DP)
● Processor modules
Features:
● 2 independent counting functions with up to 12 configurable modes (including incremental
position encoder and frequency input up to 300 kHz)
● 2 independent PWM (pulse-width modulator) or pulse outputs with push-pull driver
● Dedicated inputs/outputs for specific counting functions (e.g. touch, set, reset)
● All unused inputs/outputs can be used with the specifications of standard inputs/outputs
range
For use in extreme ambient conditions (e.g. wider temperature and humidity range), a special
XC version of the device is available.
Depending on the configuration used, some inputs and outputs are dedicated to specific
counting functions (touch, set, reset…). All unused inputs and outputs can be used with the
specification of standard inputs/outputs range.
1.6.2.1.2 Functionality
Digital inputs/outputs 24 VDC, dedicated inputs/outputs can be used for specific
counting functions:
- Catch/touch operation, counter value stored in separate vari-
able on external event (rising or falling edge)
- Set input to preset counter register with predefined value
- Set input to reset counter register
- End value output; the output is set when predefined value is
reached
- Reference point initialization (RPI) input for incremental
encoder initialization
All unused inputs/outputs can be used with the specification of
standard input/output range.
Effect of incorrect input terminal connection: Wrong or no
signal detected, no damage up to 35 V.
Fast counter/encoder integrated, 2 counters (hardware interface with +24 VDC, +5
VDC, differential and 1 Vpp sinus input) with up to 12 configu-
rable operation modes:
- 32 bits one counter mode
- 16 bits two counter mode
- Incremental position encoder
- Absolute SSI encoder
- Time frequency meter
- Frequency input up to 300 kHz
