Introduction
H Brake Interlock Output
Timing signals interlocked with the Servomotor's ON/OFF status and rotational speed are output,
so the holding brakes of Servomotors with brakes can be operated reliably.
H Output Signal Selection
Any three output signals can be selected for output from among the following: Positioning com-
pleted 1/2, speed conformity, Servomotor rotation detection, servo preparation completed, current
limit detection, speed limit detection, brake interlock, overload warning, and warning output signals.
It is also possible to allocate multiple outputs to the same pin number. For example, the positioning
completed 1 signal and the speed conformity signal could both be allocated to pin number 1.
H Overtravel Sequence
An overtravel sequence suitable for the system can be selected. There are three deceleration meth-
ods available: Dynamic brake deceleration, free-run deceleration, and emergency-stop torque de-
celeration (parameter setting).
H Feed-forward Function and Bias (Position Control)
These functions reduce the position control time.
S Feed-forward Function
Reduces the position control time by reducing the number of pulses accumulated in the deviation
counter.
S Bias
Reduces the positioning time by adding the bias revolutions to the speed command when the devi-
ation counter value exceeds the bias addition range.
H Computer Monitoring
The special Servo Driver Communications Software enables performing parameter setting, speed
and current monitoring, speed and current waveform displays, I/O monitoring, autotuning, jogging,
and other operations from a computer. It is also possible to perform multiple-axis communications
that set the parameters and monitor operations for multiple Servo Drivers. For details, refer to user
documentation on the Servo Driver Communications Software.
H DeviceNet Option Unit
A Servo Driver can function as a slave on a DeviceNet network if a DeviceNet Option Unit
(R88A-NCW152-DRT) is mounted to it, enabling application of the Servo Driver as a network driver.
Commands can be sent via DeviceNet communications to the DeviceNet Option Unit to produce
outputs to the driver. Outputting positioning commands to the driver through the option unit connec-
tor enables positioning operations without a controller. Refer to the OMNUC W-series DeviceNet
Option Unit User's Manual (Cat. No. I538) for details.
Note The DeviceNet Option Unit is supported by W-series Servo Drivers with a software version of
r.0014 or later. Refer to 4-11-10 Checking the Version for methods of confirming the Servo
Driver software version.
H MECHATROLINK-II Compatibility
The Servo Driver can be incorporated as a Slave in a MECHATROLINK network by installing the
Yaskawa JUSP-NS115 MECHATROLINK-II Option Unit (OMRON model number: FNY-NS115) on the
Servo Driver. This enables the Servo Driver to be used as a network Servo Driver.
