Sanyo Denki: Closed Loop Stepping Systems (PB Series)
SANMOTION Model No.PB
Combines the advantages of our AC servo system and stepping motors. This series has achieved high-speed, acceleration, and deceleration, and is compact and superior in terms of cost-performance. For use in semiconductor manufacturing equipment, general industrial machinery and conveying machines.
Specification:
High Speed Positioning: High torque performance in the low speed range delivers shorter positioning time for short stroke at high hit rate applications.
Smaller System Size: Smaller system size is achievable for low speed applications due to the availability of higher torque performance in the low speed range as compared to conventional servomotors With the AC power input type, motor torque has been increased by 50% compared with our conventional product.
Stable Stand-Still: Complete stand-still motion is possible due to the availability of holding torque, a typical characteristic of stepping motors. With the AC power input type, a compensator function is built in to prevent position aberration from occurring due to load variation.
High Resolution: Able to set high resolutions. The AC model comes with electronic gear and enables users to set any resolution, according to the device.
Improved Efficiency from Current Control: Higher efficiency from low heat generation is achieved by controlling the current flow to motor according to motor load With the AC power input type, motor heat generation has been reduced for 60% compared with our conventional product.
General Purpose I/O Input: System can be easily controlled by using the general purpose I/O to designate preset point or program numbers. (AC Type R, DC Type M: 128 point DC Type R Multi-axis: 256 point)
Support For Various Operations: Comprehensive built-in amplifier functionality includes thrust control, point designation, programming, homing, holding brake control and sensor limit input.
Built-in Pulse Generation Function: A built-in pulse generation function is included in the Model No. PB Types R and M. The amplifier receives speed, acceleration/deceleration and distance as numeric data from the upper-level device, and automatically generates an optimal speed pattern according to the commands internally. Since no separate pulse generator is required, this contributes to lower system cost.
PC Interface: Parameter setting, data editing and monitoring of position and speed can be done on a PC using the bundled setup software.
