Queued Index Cycle Resulting From +, -, R Commands

Constant Velocity Cycle Resulting From M Command

Constant Velocity Cycle From 2nd M Command

Execution Times

The time for a complete cycle between command entry and result is variable, depending on number of data bytes, command type, and motion in process. One receipt of the line feed, most commands execute in less than one millisecond. The exceptions are:

Instruction	Execute Time

I, V (SPS)	3-4 ms
C0 (Reset defaults)	60 ms
C (Clear memory block)	1500 ms
S (Store)	60 ms
/, ] (Read, Write)	1.1 ms
Index +, and R	5-10 ms

Times will vary depending on product. The EASI program has a benchmark feature that can be used to determine times.
