ΔΣ integral method 1 to 99 1 points [Varies depending on model.] Functions can be set for each CTL for external control. Hold (current/max./min. value, max. fluctuation range) ON when control input (CTL*) pin (ON logic) is shorted to GND; setting is reflected when open. Command control is possible via communication (USB, CAN, RS-485) Commands set via communication cannot be released by terminal input. Reset execution is always required. Response time can be set: 1 to 1999 ms Possible to back up values during shift operations. (values can be retained even when power is turned off) Nonvolatile memory (EEPROM) |
