Use of Gear Absolute (25) Command
1: Can Gear Absolute (25) be called once to establish the gear relationship between the master axis and the slave axis, there is no need to call it cyclically?
In the project, Gear Absolute (25) must be called cyclically to run normally? What is the reason?
2: How to break the gear relationship between the master axis and the slave axis. At present, I use the hold position command to interrupt the slave axis. Is this correct?
There is no need to call the Gear Absolute cyclically. In fact, it is usually a bad idea to do that, because the Transition will kick in each time and will likely cause the slave axis to not follow the master very well.
To break a gearing relationship, simply send a different motion command. If the axis is moving, don’t use the Hold Current Position command, since it will cause an abrupt stop - use the Stop (Closed-Loop) command instead.
If the Gear Absolute command needs to be sent cyclically in your project in order to run, you probably have something else going on, such as another command that is interrupting it, or an axis halt.
