NOTE
• When Pr.541 = 1 (with sign)
When EEPROM 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 turning OFF the power (inverter reset).) When set frequency
is written with the instruction code of HED and HEE, the sign of the frequency command is not changed.
