CAUTION
Use wires and cables within the length of the range described in the instruction manual.
The ratings and characteristics of the system parts (other than control unit, servo amplifier,
servomotor) must be compatible with the control unit, servo amplifier and servomotor.
Install a cover on the shaft so that the rotary parts of the servomotor are not touched during
operation.
There may be some cases where holding by the magnetic brakes is not possible due to the
life or mechanical structure (when the ball screw and servomotor are connected with a
timing belt, etc.). Install a stopping device to ensure safety on the machine side.
(2) Parameter settings and programming
CAUTION
Set the parameter values to those that are compatible with the control unit, servo amplifier,
servomotor and regenerative resistor model and the system application. The protective
functions may not function if the settings are incorrect.
The regenerative resistor model and capacity parameters must be set to values that
conform to the operation mode, servo amplifier and servo power unit. The protective
functions may not function if the settings are incorrect.
Set the mechanical brake output and dynamic brake output validity parameters to values
that are compatible with the system application. The protective functions may not function if
the settings are incorrect.
Set the stroke limit input validity parameter to a value that is compatible with the system
application. The protective functions may not function if the setting is incorrect.
Set the servomotor encoder type (increment, absolute position type, etc.) parameter to a
value that is compatible with the system application. The protective functions may not
function if the setting is incorrect.
Set the servomotor capacity and type (standard, low-inertia, flat, etc.) parameter to values
that are compatible with the system application. The protective functions may not function if
the settings are incorrect.
Set the servo amplifier capacity and type parameters to values that are compatible with the
system application. The protective functions may not function if the settings are incorrect.
Use the program commands for the program with the conditions specified in the instruction
manual.
Set the sequence function program capacity setting, device capacity, latch validity range, I/O
assignment setting, and validity of continuous operation during error detection to values that
are compatible with the system application. The protective functions may not function if the
settings are incorrect.
Some devices used in the program have fixed applications, so use these with the conditions
specified in the instruction manual.
The input devices and data registers assigned to the link will hold the data previous to when
communication is terminated by an error, etc. Thus, an error correspondence interlock
program specified in the instruction manual must be used.
Use
the interlock program specified in the special function unit's instruction manual for the
program corresponding to the special function unit.
