Mps

Function

To convert the designated speed value (mm/sec) to the ratio (%) relative to the maximum internal speed in CP motion.

Syntax

Mps(speed)

Guaranteed Entry

Speed: Designate the speed value (mm/sec) by single precision real number type data.

Return Value

Return the internal speed value (%) by single precision real number type data.

Description

The designated speed value (mm/sec) is converted to the ratio (%) relative to the maximum internal speed in CP motion.

Calculation is on the assumption that the external speed is 100%.

The speed can be specified by the speed value (mm/sec) in combination with speed specification command "SPEED."

Attention

Any extended-joints are not considered.
If this command is used with SPEED command, note that the following points.

Be careful about the input range of SPEED command. If the value entered in this Mps command is too small, the entered value might be out of the input range of SPEED command. As a result, an error might occur at the execution.
If the payload is changed, the maximum speed will be changed accordingly, that leads to the change of the return value of this command. As a result, the return value might be the outside of the input range of the SPEED command.
The acceleration is equal to the square of the speed. If too small value is specified to this command, the acceleration becomes small as well. As a result, it might fail to reach the specified speed. In this case, adjust the acceleration.
