Item Description
Restrictions or precautions • This FB does not include the error recovery processing. Program the error recovery processing separately in accordance
with the required system operation.
• This FB cannot be used in an interrupt program.
• Do not use this FB in programs that are executed only once, such as a subroutine program or FOR-NEXT loop, because
i_bEN (Execution command) cannot be turned off and the normal operation cannot be acquired. Always use this FB in
programs that can turn off i_bEN (Execution command).
• This FB turns on and off Forward run JOG start signal (Cd.181: Forward run JOG start signal) and Reverse run JOG start
signal (Cd.182: Reverse run JOG start signal) Thus, do not turn on or off Forward run JOG start signal (Cd.181: Forward run
JOG start signal) and Reverse run JOG start signal (Cd.182: Reverse run JOG start signal) by other means while this FB is
being executed.
• When this FB is used twice or more, precaution must be taken to avoid duplication of the target axis.
• Setting a large value for the JOG speed from the beginning is dangerous. For safety, set a small value first, and increase the
value gradually while checking the operation to determine the value optimal for the control.
• When values other than 0 are set in both i_uInching (Cd.16: Inching movement amount) and i_udJogSpd (Cd.17: JOG
speed), the inching operation is performed.
• Every input must be provided with a value for proper FB operation.
• The pulse output mode and external input/output signal logic, etc. must be set according to the connected devices and
system before operating the positioning module. Set the GX Works3 module parameters according to the application. Refer
to the MELSEC iQ-F FX5 User's Manual (Positioning Control - Intelligent function module) for details on setting the
module parameters.
Error code
Error code (hexadecimal) Description
100 The set value of i_uAxis (Target axis) is out of the range.
The target axis is not within the range of 1 to 4.
Action
Try again after checking the setting.
Turn off the forward run JOG command or reverse run JOG
command, turn on i_bEN from off, and turn on the forward run
JOG command or reverse run JOG command again.
