Parallel connection: Several primary parts in parallel
The arrangement of two or more primary parts on one drive controller in con‐
junction with a linear scale is known as parallel arrangement.
① Control unit
② Controller
③ Length measuring system

conjunction with a length measuring system
To ensure successful operation, the following conditions must be fulfilled:
●
Use identical primary parts MCP and same line length MCS
● Stiff motor coupling within the axis
● Position offset between the primary parts <1 mm in feed direction
● Position offset between the secondary parts <1 mm in feed direction
● If possible, load stationary and arranged symmetrically with respect to
the motors
The determination of the distance that must be adhered depends on the di‐
rection of the cable outlet and the permissible bending radius of the power
cable.
