NOTES
When Pr. 541 = 1 (with sign)
● When E²PROM write is specified with the RYE, write mode error (error code H01) will occur.
● When concurrent execution of both RYD and RYE is enabled (when a value other than 0 is set in
Pr. 544) and both RYD and RYE are turned on, RYD has precedence.
● When power is turned on (inverter reset), the initial setting status of the sign bit is "positive"
and the set frequency is "0 Hz". (The motor does not operate at the frequency set before turn-
ing OFF the power (inverter reset).)
● When set frequency is written with the instruction code of HED and HEE, the sign of the fre-
quency command is not changed.
