These function codes specify various parameters required for synchronous operation. For details, refer to the PG Interface
Card instruction manual.
d70
Speed Control Limiter
d70 specifies a limiter for the PI value output calculated in speed control sequence under V/f control with speed sensor or
dynamic torque vector control with speed sensor.
A PI value output is within the "slip frequency
×
maximum torque (%)" in a normally controlled state.
If an abnormal state such as a temporary overload arises, the PI value output greatly fluctuates and it may take a long time
for the PI value output to return to the normal level. Limiting the PI value output with d70 suppresses such abnormal
operation.
Data setting range: 0 to 100 (%) (assuming the maximum frequency as 100%)
