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.
11.6.1 Total weight (mover + load)
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.
11.6.2 E-Gear ratio
It is suggested to set the E-Gear ratio for the linear motor to
P1.044
P1.045
=

. If the E-Gear ratio is 1,
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.
11.6.3 Limit setting
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.
