Linear Motor

11.6 Parameter setting

Linear motors and rotary motors are incompatible with specific parameter settings. The following

sections describe the definitions and precautions for linear motor parameter settings. Before

setting the parameters, refer to Chapter 8 Parameters for more information. Some settings and

units of the parameters for the linear motor are different from those of the rotary motor, which

are further explained in this section.

The total weight estimation of the linear motor is similar to that of the rotary motor, but the set

unit for the total weight of the linear motor is kg. The suggested speed during estimation is

10000 (0.01 mm/s) or above, the acceleration or deceleration speed is 0 - 5000 mm/s, and the

duration is less than 1.5 seconds.

It is suggested to set the E-Gear ratio for the linear motor to

when the command issues 1 PUU, the linear scale feedback is 1 pulse; if the E-Gear ratio is 2,

when the command issues 1 PUU, the linear scale feedback is 2 pulses. Incorrect E-Gear ratio

setting may result in an error between the command and the actual movement distance.

The limit setting function is to protect the motor from exceeding the allowable range. Use the

actual signal switch to connect to the DI for protecting the machine and avoiding collision.

As shown in the following figure, the X and Y of the DI are user-defined. The DIX in this figure is

defined as the positive limit (PL) and the DIY is defined as the negative limit (NL). These two

functions are defined as forward inhibit limit (0x23) and reverse inhibit limit (0x22). When the

forward or reverse direction changes, change the positive and negative limit settings, otherwise

there is no protection.
