Retry Count Setting - Mitsubishi Electric FR-XC-18.5K-PWM Instruction Manual

Retry count setting (Pr.121)
• Set the permissible number of retries at data receive error occurrence. (Refer to
enables retry.)
• When the data receive errors occur consecutively and exceed the permissible number of retries set, the converter outputs
the Alarm (LF) signal. (The converter does not shot off its output.)
• When a data transmission error occurs while "9999" is set, the converter outputs the Alarm (LF) signal. (The converter does
not shot off its output.)
To use the LF signal, set "98 (positive logic) or 198 (negative logic)" in any of Pr.11, Pr.12, and Pr.16 (Output terminal
function selection) to assign the function to an output terminal.
Example: PU connector communication when Pr.121 = "1 (initial value)"
