NOTE
• When Pr.541 = "1" (with sign)
• When EEPROM write is specified by turning ON of RYE, write mode error (error code H01) will occur.
• When both RYD and RYE are turned ON while both of them are enabled (Pr.544 ≠ "0"), 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 or HEE, the sign of the frequency command is not changed.
