operations.

REGENERATIVE BRAKE OPTION
This function is an option. It is used when carrying
out highly repetitive acceleration/deceleration.
RESOLVER
This device detects the angle by resolving the two
voltages of an analog input. Also called a 2-phase
synchro. For a 1-phase voltage input, the axis
rotation angle is converted into a perpendicula
r
2-phase voltage (analog voltage) and output.

A servo unit will not operate if the drive unit is in an
abnormal state and this servo ON signal is OFF.

SKIP FUNCTION
When the SKIP signal is input, the positioning
being executed is interrupted, the motor is
decelerated to stop, and the next positioning is
automatically carried out.
SPEED CONTROL
Normally, speed control is for controlling the speed
of a servomotor. For example, it controls grindstone
rotation, welding speed, feedrate, etc. Unlike
position control, in speed control the curren
t
position (address) is not controlled.
SPEED INTEGRAL COMPENSATION
One of the servo parameters of the positioning
data, and is used to raise the frequency response
during speed control to improve transien
t
characteristics.
When adjusting the speed loop gain, raising this
value is effective if the overshooting during
acceleration/deceleration remains large.
This compensation is set in the units of ms.
SPEED LIMIT VALUE
The max. speed for positioning. Even if other data
is mistakenly set to a higher speed than this, the
positioning will be carried out at this speed limi
t
value when it is set in the parameters. The
acceleration time is the time to accelerate from a
stopped state to the speed limit value, and the
deceleration time is the time to decelerate from the
speed limit value to a stopped state.
SPEED LOOP GAIN
One of the servo parameters of the positioning
data. It represents the speed of the control
response during speed control. When the load
inertia moment ratio increases, the control system
speed response decreases and the operation ma
y
become unstable. If this happens, the operation
can be improved by raising this setting value.
The overshoot will become larger if the speed loop
gain is raised too far, and motor vibration noise will
occur during operation and when stopped.
STEP FUNCTION
When the operation is designed so that several
positioning data Nos. are consecutively started, this
function can be used to carry out test operation fo
r
1 data item at a time.
