Bit
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.

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.
