System Parameters
Section 4-2
Explanation
• Sets the unit cycle time.
• Only setting the longer time than the time set automatically is valid.
• This parameter is set to use the same cycle time (i.e., the same perfor-
mance) for two or more MC Units when the MC Units control different
numbers of axes.
Example:
Cycle time calculated for MC Unit 1: 1 ms
Cycle time calculated for MC Unit 2: 2 ms
In this case, the cycle time for MC Unit 1 would be set to 2 ms.
• The time set automatically will be reflected in the system variable
SW0000. (See 4-5 System Variables for details.)
For details of the enabling condition, see 1-7 Performance Calculation Method
for Unit Cycle on page 21.

Bit Function and explanation
00 Helical circular interpolation speed
(Sets the method for specifying the speed in helical circular interpolation executed with MOVEC com-
mand.)
0: Speed on the circumference
1: Tangential speed
01 Circular interpolation center position
(Sets the method for specifying the center position for MOVEC command.) Refer to the description of
the MOVEC command for details.
0: Always specify relative positions.
1: Specify relative or absolute positions.
02 Speed command value
(Specifies the speed command unit for SPEED command and the unit for feedback speed 2 and
speed command 2 in present value monitoring.)
0: Rated % specified
1: r/min specified
03 Communications cycle support
Specifies the communications cycle.
Normally set this parameter to 1. A setting of 0 is provided for compatibility with the CS1W-MCH71.
0: Support 1 ms, 2 ms, and 4 ms communications cycles.
1: Support 1 ms, 2 ms, 3 ms, and 4 ms communications cycles.
