ALPHA5 | Features
Compatibility with general-purpose communication:VV type
Simple! PTP positioning
Positioning function is embedded as standard in general purpose interface unit "ALPHA5 VV".
As the ALPHA5 VV type is the standard model, external positioning unit or dedicated items for positioning are not required.
3 in 1!
Following operations are enabled by one unit:
- Positioning via Modbus-RTU communications (immediate value data)
- Positioning via Di/Do signal (positioning data 15 points*)
- Controlling positions, speeds and torques via pulse/analog input
Simple connection! Modbus-RTU communications
Operations such as PTP positioning operation, parameter edit, and various monitoring are enabled. All you need to do is connect HMI (POD), general-purpose PLC, or PC controller directly to servo amplifier via Modbus-RTU communications.
Compatibility with SX bus:VS type and LS type
Operations such as PTP positioning operation, parameter edit, and various monitoring are enabled.
All you need to do is connect HMI (POD), general-purpose PLC, or PC controller directly to servo amplifier via Modbus-RTU communications.
Fast and accurate positioning is realized
New high speed servo control engine
Frequency response 1500Hz
Increased motor rotation speed
Max. rotation speed 6000r/min
Fine resolution encoder
18-bit absolute 262,144 pulses
20-bit incremental 1,048,576 pulses
High performance frequency response (1500Hz), high rotation speed (6000r/min) and high resolution encoder reduce the cycle time and make faster and more accurate positioning and settling possible.
■MCycle time reduction 1.2s -> 1s
■MTime necessary to settling to 1em accuracy 4ms
New control functions
New notch filter (auto notch filter)
The notch filter is set automatically upon detection of mechanical resonance.
Because detection and calculation are always conducted while the auto notch filter remains turned on, resonance frequencies changing by time are effectively filtered.
Homing by hit-to-stop
Wire saving can be achieved with elimination of the limit switch and over travel signal. Moreover, several homing functions allows homing program creation to be simplified only by combining the servo parameters. Creating complicated program of homing in the host controller is no more necessary.
Motor stop method setting is enabled
- Alarm occurrence
- Main power supply is OFF.
- Servo ON signal is OFF.
* However, it is enabled when the control power supply is input.
