Note Thyristors
Thyristor and varistor are used for loads when induction

when power is cut off is approximately 1.5 times that of
the varistor.
Use capacitors and resistors for vibration absorption of
surge when power is cut off. The reset time can be
shortened by proper selection of the capacitor or resistor. Used for 100/200-VAC circuit contactors.
and varistors are made by the following companies. Refer to manufacturers documentation for
Select leakage breakers designed for inverters.
Since switching operations take place inside the Servo Driver, high-frequency current leaks from the
armature of the Servomotor. With inverter leakage breakers, high-frequency current is not detected,
preventing the breaker from operating due to leakage current.
When
selecting leakage breakers, remember to also add the leakage current from devices other than

3-5-4Electronic Gear Function: Position Control
H Function
• The motor will be driven with a pulse determined by multiplying the command pulse count by the
electronic gear ratio.
• The electronic gear is useful for the following applications:
S To fine-tune the position and speed of two lines that must be synchronized.
S When using a positioner with a low command pulse frequency.
S To set the machine movement per pulse to a specific value, such as 0.01 mm.
H Setting User Parameters
• The
electronic gear is set as G1 divided by G2
in Cn-25. The target pulse count is computed as follows:
Target pulse count = Command pulse count x G1/G2
(G1/G2). G1 is set in user parameter Cn-24; G2 is set
• If
G1/G2 = 1, the motor will turn once for every 8,192 command pulses (driver running at a factor of
4X).
• One
pulse for the position deviation (deviation counter) display and positioning completion range will
be equivalent to one input pulse (here the unit is said to be the command).

The bias function shortens positioning time by adding the bias rotational speed to the

command when the residual pulses in the deviation counter exceed the position

H Function
• When
the residual pulses in the deviation counter exceed the positioning completion range (Cn-1b),
this function adds the bias rotational speed (Cn-1C) to the speed command. When the pulses are
within the positioning completion range, it stops adding the bias rotational speed.
