Separate Type ABS ST Series
Absolute Scale Unit (High environmental resistance type)ABS ST700 Compact Type Series
Features

Scale base type

• Absolute measurement with separate type scales• Non-contact detection is optimal for high speed and high acceleration of linear motors, etc.
• Electromagnetic induction principle means scales are unaffected by contamination• The detector head is approximately 1/3 the previous model size: 50mm (W) × 28mm (D) × 11mm (H)• Cable outlets can be in four directions, with mounting holes on the top and sides• Accuracy (5+5L/1000)μm is realized (previous models: (8+5L/1000) μm)*L: Effective range (mm)• Compatible with servo amplifiers from a range of companies (high-speed serial interfaces)

Signal Adjusting Method When Mounting ABS ST700 Series• In order to perform signal adjustment and confirmation after the unit is mounted, conditioning is necessary using a PC andapplication software (ABS ST700 Signal Adjustment Program). (For conditioning, allow a travel distance of at least 60mm.)
The following settings and confirmation are possible with this software:
1) Scale signal automatic adjustment ➞ It is necessary to mount the scale base and detector head detector with specified
dimensions.
2) Scale signal amplitude (signal strength) confirmation
3) Scale origin (absolute position data of zero) setting4) Absolute position data confirmation
5) Error history clear

Compatibility of Detector Head and Main Scale• Note that for the ST700 series (compact type) with an
AC100Veffective range 3000 mm
or less or 3200 mm or more,
the main scale and the detector head are different so they
are not compatible.
• The communication standards are different for the ST7(L) and ST7A (L), so they are not compatible.
