5.3 Description of Function Codes 5.3.5 H codes (High performance functions)
For adjustment by manufacturer
H86, H89, and H90 are reserved for adjustment by the manufacturer. Unless otherwise specified, do not access
these function codes.
Current input wire break detection
Terminal [C1] (C1 function) (current input) wire break can be detected and processed as an alarm.
If using an analog interface card (OPC-AIO), wire break can be detected for both terminal [C2] and terminal [C1] in
the same way and processed as an alarm (Cof alarm).
If a current input wire break is detected, Y terminal function “C1OFF” is output based on the o88: C1OFF signal
operation selection setting.
Function code H91 specifies whether the wire break detection is enabled, and the duration of detection.
A wire break is detected if the terminal [C1] and [C2] current input is less than 2 mA.
The Cof alarm can also be assigned as a warning with H82. If a wire break is detected, cof appears on the keypad,
and warning “L-ALM” is output to notify the user.
This is only effective if used with C40 = 0 or 10 (4 to 20 mA).
• Data setting range: 0.0 (Disable wire break detection)
0.1 to 60.0 s (Detect wire break and issue of alarm cof within the time)
Continuous running at the momentary power failure (P, I) (Refer to F14)
The continue to run (P, I) setting is described in detail in the function code F14 section.
Cumulative motor run time 1 (Refer to H78)
The motor cumulative run time 1 setting is described in detail in the function code H78 section.
DC braking (Braking response mode) (Refer to F20 to F22)
The DC braking setting is described in detail in the function code F20 to F22 section.
