H
Electronic Gear Function
The number of pulses used to rotate the motor is calculated by multiplying the number of command
pulses by the electronic gear ratio. This function is useful in the following kinds of cases.
j
When you want to finely adjust the position and speed of two lines that need to be synchronized
j
When you want to increase the control pulse frequency of a controller with a low pulse frequency
j
When you want to set the movement/pulse to a certain amount, such as 0.01 mm/pulse
The electronic gear ratio is set with parameters G1 and G2 (G1=numerator and G2=denominator).
The setting range for parameters G1 and G2 is 1 to 65,535. The setting range for the gear ratio is
0.01 to 100, i.e., 0.01
x
G1/G2
x
100.
H
Pulse Smoothing Function
Even high-frequency commands can be executed smoothly by including acceleration/deceleration
in the command pulses. The same setting is used for both the acceleration and deceleration times,
and the setting range is 0 to 64 ms.
H
Reverse Mode
Forward/Reverse commands can be switched in the parameters, without changing the wiring to the
motor or encoder.
H
Brake Interlock Output
Outputs a timing signal interlocked with the motor’s ON/OFF status and rotational speed. The hold-
ing brake of a motor with a brake can be operated reliably.
H
Computer Monitor Software
The special Servo Driver Communications Software allows parameter setting, speed and current
monitoring, I/O monitoring, auto-tuning, and jog operations to be performed from a personal com-
puter. It is also possible to perform multiple-axis communications that set the parameters and moni-
tor the operation of several drivers. Refer to the
Computer Monitor Software Instruction Manual
(I513) for OMNUC U-series Servo Drivers for more details.
Note Version 1.1 or later of the Computer Monitor Software supports the UE Models.
