Hold the constant peripheral speed control frequency in the memory LSC-HLD
(Function code E01 to E07, data = 71)
If this signal is ON under constant peripheral speed control, stopping the inverter (including an occurrence of an alarm
and a coast-to-stop command) or turning OFF
Hz/LSC saves the current frequency command compensating for a
take-up roll getting bigger, in the memory. At the time of restart, the saved frequency command applies and the inverter
keeps the peripheral speed constant.
LSC-HLD Function
OFF Disable (no saving operation)
ON Enable (Saving the frequency command compensating for a take-up roll getting bigger)
Shutting down the inverter power during an operation stop loses the frequency compensation data saved in the
memory. At the time of restart, therefore, the inverter runs at the frequency without compensation so that a
large overshoot may occur.

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. To suppress such abnormal operation, the PI value output can
be limited with d70.
Data setting range: 0 to 100 (%) (assuming the maximum frequency as 100%)

Customizable Logic Timer Monitor (Step selection)
The customizable logic function allows the user to form a logic circuit for digital input/output signals, modify them
arbitrarily, and configure a simple relay sequence inside the inverter.
In a customizable logic, one step (component) is composed of "2 inputs and 1 output + logical operation (including
timer)" and a total of ten steps can be used to configure a sequence.
