Reset UP/DOWN frequency -- STZ (Function code data = 58)

Turning the STZ ON clears the frequency increase or decrease from the "Multistep frequency
+ UP/DOWN control." (This command merely clears the increase or decrease so that the
reference frequency may not come to be 0 Hz.)
 Refer to F01 and H61.
Count the run time of commercial power-driven motor 1

-- CRUN-M1 (Function code data = 72)
The CRUN-M1 enables the inverter to count the cumulative run time of motor 1 even when it
is driven by commercial power (not by the inverter).
When the CRUN-M1 is ON, the inverter judges that motor 1 is driven by commercial power
and counts the run time of the motor.
Cancel customizable logic -- CLC (E01 to E07, data = 80)

The CLC disables the customizable logic temporarily. Use it to run the inverter without using
the customizable logic circuit or timers for maintenance or other purposes.
CLC
OFF Enable customizable logic (Depends on the U00 setting)
ON Disable customizable logic
Before changing the setting of CLC, ensure safety. Turning CLC ON disables the
sequence of the customizable logic, causing a sudden motor start depending upon
the settings.
Clear all customizable logic timers -- CLTC (E01 to E07, data = 81)

Assigning CLTC to any of the general-purpose digital input terminals and turning it ON
resets all of the general-purpose timers and counters in the customizable logic. Use this
command when the timings between the external sequence and the internal customizable
logic do not match due to a momentary power failure or other reasons so that resetting and
restarting the system is required.
CLTC
OFF Ordinary operation
Reset all of the general-purpose timers and counters in the customizable logic.
ON
(To operate the timers and counters again, revert CLTC to OFF.)
Run command 2/1 -- FR2/FR1 (Function code data = 87)

The FR2/FR1 switches between the run command source selected by Run command (FWD
and REV) and the one selected by Run command 2 (FWD2 and REV2).
