TROLINK communications error, Unit setting error
Purpose
Category
Name
Basic function
Details
Establishing the
mechanical origin of
the machine
Origin deter-
mination
Origin search
The motor is operated to estab-
lished the origin.
8-2 Origin Search
Operation
Present position preset
The position where the motor is
stopped is set to a specified posi-
tion to establish the origin.
8-3 Present Position
Preset
Origin return
The axis is returned to the estab-
lished origin.
8-4 Origin Return
Absolute encoder origin
The origin is established using a
Servomotor with an absolute
encoder, so origin searches are
not required at machine startup.
8-6 Absolute
Encoder Origin
Point-to-point (PTP)
positioning
Position con-
trol
Direct operation (abso-
lute movement or relative
movement)
The position and speed are speci-
fied to perform positioning using
an absolute or relative movement.
9-4 Using Direct
Operation
Changing the target
position and speed
as required during
positioning
Direct operation:
Changing target position
or changing target speed
The target position or target
speed is changed during position-
ing with direct operation.
9-4-3 Changing Tar-
get Position
9-4-4 Changing Tar-
get Speed
Performing position-
ing for a specified
distance from an
external input point
during positioning
Interrupt feeding
When an interrupt input signal
turns ON during positioning with
direct operation, operation
switches to positioning for a fixed
amount.
9-5 Interrupt Feeding
Performing manual
feeding for adjust-
ment or other pur-
pose
Jogging
The axis is moved at a fixed
speed in the forward rotation or
reverse rotation direction.
10-2 Jogging
Reducing shock
while device is oper-
ating
Auxiliary
functions
Acceleration/decelera-
tion curves
Acceleration/deceleration is per-
formed according to the basic
trapezoidal curve (linear accelera-
tion/deceleration), an exponential
curve, or an S-curve, which
greatly helps to reduce mechani-
cal vibration.
7-4 Acceleration and
Deceleration Opera-
tions
Temporarily multiply-
ing the machine's
operating speed by a
constant ratio to per-
form startup adjust-
ments
Overrides
The axis command speed is mul-
tiplied by a constant ratio.
10-3 Override
Restricting output
torque during con-
trol operations such
as pushing control
Torque limit
A constant limit is applied to the
output torque of the Servomotor
during positioning.
10-4 Torque Limits
Stopping the device
during operation
Stop func-
tion
Deceleration stop or
emergency stop
The moving axis is decelerated to
a stop or the axis is moved for the
number of pulses remaining in the
deviation counter and then
stopped.
10-9 Stop Functions
Changing the Servo
Drive settings from
the PLC
Data transfer
function
Reading/writing Servo
parameters
Servo Drive parameters are read
or written from the CPU Unit.
5-3 Transferring
Servo Parameters
