No Spec: Unidirectional Posit.; No F Command; No Spec: High Speed Mode 3; F Value Is Exceeding The Limit - Mitsubishi Electric M800 Series Manual

M800/M80/E80/C80 Series Alarm/Parameter Manual
12 Program Errors (P)
P61

No spec: Unidirectional posit.

Details
Unidirectional positioning (G60) was commanded while the function is out of specifications.
Remedy
Check the specifications.
P62

No F command

Details
No feed rate command has been issued.
There is no F command in the cylindrical interpolation or polar coordinate interpolation immediately after
the G95 mode is commanded.
Remedy
The default movement modal command at power ON is G01. This causes the machine to move without
a G01 command if a movement command is issued in the program, and an alarm results. Use an F com-
mand to specify the feed rate.
Specify F with a thread lead command.
P65

No spec: High speed mode 3

Details
Remedy
Check whether the specifications are provided for the high-speed mode III.
P67

F value is exceeding the limit

Details
F's value in an F or ,F command is exceeding the command range.
Remedy
Check and correct F or ,F command in the program.
P70 Arc end point deviation large
Details
There is an error in the arc start and end points as well as in the arc center.
The difference of the involute curve through the start point and the end point is large.
When arc was commanded, one of the two axes configuring the arc plane was a scaling valid axis.
Remedy
Correct the numerical values of the addresses that specify the start and end points, arc center as well as
the radius in the program.
Correct the "+" and "-" directions of the address numerical values.
Check for the scaling valid axis.
P71 Arc center error
Details
An arc center cannot be obtained in R-specified circular interpolation.
A curvature center of the involute curve cannot be obtained.
Remedy
Correct the numerical values of the addresses in the program.
Correct the start and end points if they are inside of the base circle for involute interpolation. When carrying
out tool radius compensation, make sure that the start and end points after compensation will not be inside
of the base circle for involute interpolation.
Correct the start and end points if they are at an even distance from the center of the base circle for involute
interpolation.
