Refer to the PLC function programming manual.
Frequency command with sign (Pr.541)
• The start command (forward/reverse rotation) can be inverted by adding a plus or minus sign to the value of the frequency
command sent through the CC-Link IE Field Network Basic.
• The Pr.541 Frequency command sign selection setting is applied to the frequency command from RWw1. (Refer to
page 58.)

Pr.811 is only available for the FR-A800-E.
• Relationship between the start command and sign (Pr.541="1")
Start command
Forward rotation
Reverse rotation
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.
• Setting Pr.811 Set resolution switchover ="1 or 11" changes the increment from 1 r/min to 0.1 r/min.
