Introduction
H Monitor Output
The offset and scaling of the analog monitor outputs can be adjusted.
H Multi-turn Limit Changes
The multi-turn limits for absolute encoders can be changed.
H Electronic Gear (Position Control)
This function turns the Servomotor by the number of pulses obtained by applying the gear ratio to
the number of command pulses. It can be effectively used in the following situations.
S When fine tuning positions and speeds while synchronizing two lines.
S When using a controller with a short command pulse frequency.
S When setting the mechanical movement per pulse to amounts such as 0.01 mm.
The electronic gear ratio is set in parameters (numerator: G1; denominator: G2). The setting range
for G1 and G2 is 1 to 65,535, with 0.01 x (G1/G2) x 100.
H Encoder Dividing Function
The encoder signal output from the Servo Driver can be set to the desired number of pulses.
H Soft Start Function (Speed Control, Internally Set Speed Control
Settings)
This function causes the Servomotor to be started and stopped at the preset acceleration/decelera-
tion times, allowing a simple position control system to be constructed without a Positioner or Host
Controller.
The acceleration and deceleration times are set separately, and the setting range is 0 to 10 s for
each.
H Position Acceleration/Deceleration Function
Applying acceleration and deceleration to command pulses enables smooth tracking of commands
for rapid startups. Either primary delay or linear acceleration/decelerations can be selected for posi-
tioning.
H Warning Output
Overload and regeneration overload warnings are output. When a warning is output, taking mea-
sures, such as shortening the operation cycle, can prevent an alarm from being generated.
H Positioning Completed Output
The positioning completed range can be set in two stages, allowing peripheral device operations to
begin sooner.
H Reverse Mode
Forward and reverse commands can be switched in the parameters, without changing the wiring to
the Servomotor or encoder.
