8 Command Reference

Truncate

If the master moves

past an endpoint, the

slave axis' Target

Position will stop at the

endpoint. When the

master moves back into

the range, the gearing

will resume. If the

master is moving

quickly when it exceeds

the endpoint, it may

cause the slave to stop

abruptly.
Note:

If a superimposed

transition is used, in

certain cases it can

cause the slave to

exceed the endpoints

during the transition. If

this causes problems,

consider using a

different type of

transition.

Extrapolate The slave will always

follow the master on the

linear relationship.


Related Commands
With the Gear Absolute command, the Target Position will follow the master value

exactly. If the master is noisy, or exceeds the position, velocity, or acceleration limits of

the slave axis, this can cause problems. In this case, consider using the Track Position

(57) or Track Position (I-PD) (58) commands, which provide limits on the slave axis

motion.
See the Gearing Overview topic for general information about gearing, including possible

Gear Masters.

Specifying a Register Address

When issuing this command from anywhere other than RMCTools, the addresses in the

Master Register command parameter must be entered as an integer value.
RMC addresses are represented in IEC format as:

%MDfile.element, where file = file number, and element = element number.

Use the following equation to convert a register address to integer format, N:

N = file * 4096 + element


Example:
Register address %MD8.33 is 8*4096 + 33 = 32801.
