LONWORKS® built-in board option
(LIU005Z-1) communication manual
Maximum quality - maximum performance
The S11 adjustable speed drive provides maximum torque with
precise speed control. It features an easy-to-use, quiet, and compact
design. In addition, the S11's advanced technology allows for
versatile communication. No other micro-drive delivers such reliable
performance and extensive capabilities at such a competitive price.
Powerful True-Torque Control
• 250% Torque at 1.0 Hz
• One-Step Motor Auto-Tuning
• 0.1% Speed Regulation on 60:1 Speed Range
Initial torque surpasses 1 Hz through 200%* instantly at startup from low
speed. Smooth operation in the regeneration area and in the motoring
area is possible through proprietary power vector control. Equipped with
an energy savings mode, applications reach a higher level of efficiency.
In addition, you can activate auto-tuning and automatic torque-boost
in a single step.
*When Running Standard Toshiba 4-Pole Motor (Depending on Voltage and Rating)
• Drooping: Configurable Bipolar Drooping with Adjustable Bandwidth
• Volts/Hz: Constant Torque, Variable Torque, Automatic Torque-Boost, Sensorless Vector
Control, Automatic Energy Savings, and Permanent-Magnet Motor Control
• Start/Stop: Three-Wire Control, Digital Input, Local Panel, and Communications
• Frequency Setting: Built-In Potentiometer, 4 to 20 mA, 0 to 10 V, Motor-Operated
Potentiometer, Serial Communication, and Jog Mode
• Bidirectional Speed Searchable to Detect a Spinning Motor and Start at that Speed
Regardless of Direction
• PID Control with Built-In 24 VDC Power Supply for Process Transducer
• Dynamic Brake-Chopper Transistor Standard on All Models
A warning signal is sent to the display panel when
the electrolytic capacitors on the main
circuit, the cooling fan, or the control board reach
the replacement period. This valuable
indicator can be used as a maintenance guideline.
The cooling fan is replaced easily, and
the automatic on/off function provides extended
product life. The S11 is a long-life drive
and its main circuit capacitors are designed to have
a 10-year lifetime.* It is designed to
be used in ambient temperatures up to 60˚C for
(with minimum current derating required).
The S11’s design allows the user to connect a
motor, apply power, connect a motor, and
run the drive right out of the box.
It has an easy-to-use customer terminal
strip for integration into complicated
applications, and its small footprint and
side-by-side mounting capabilities make it an
excellent OEM product.
Built-In EMI Noise Filter
The S11 is the best in its class when it comes
to environmental considerations. All S11 units
are equipped with a high attenuation
RF/EMI noise filter. Single-phase and 500 class
devices include filters that bring the drive
into compliance with Class A, Group 1 to
satisfy the CE EMC directive.*
*Depending On Motor Cable Length
The S11 saves space with its reduced dimension compact design.
Multiple units can be mounted side-by-side for high-density installation.
The compact design does not hinder its capabilities. The S11's high
functionality and user-friendly features make it a top-class drive.
External communication modules are available with functionality
for multiple drive connectivity. Available protocols are Ethernet
TCP/IP, Ethernet IP, DeviceNet, Modbus Plus, Modbus RTU,
Metasys, Landis and Staefa, and Profibus DP. These interfaces
are already used extensively on 7-Series and 9-Series Toshiba
