DATA CONVERSION

RESPONSE TIME

Response time of analog input module is time from when 0 to 100% stepwise signal change is applied to the analog module till when the communication ASIC of the module (slave) transmits 90% of input signal.
TCOM: MECHATROLINK-III transmission cycle set at master
(depends on system and configuration)

TINP: Input module response time ≤  Input Delay time (Ta) +  Conversion rate*1 (Tb) + input internal processing delay time (Tc) (two transmission cycle)

*1. Conversion rate x Averaging

E.g.: Averaging (2), input delay time of 20 msec, transmission cycle of 0.5 msec.
Input module response time (TINP): Input Delay time (20 msec.) + Conversion rate (0.5 msec.) × Averaging (2)
+ internal processing delay time (0.5 msec. x 2) = 22 [msec.]

I/O DATA DESCRIPTIONS

Scaling of analog I/O module is configurable with the configurator software (model: R7CFG). Refer to the software manual for details.
