0x8180-02 – Gear unit factor

Gear unit factor for standardizing position, speed and acceleration values. The value represents the "units" (in thousands) that a rotary axis needs to make exactly one revolution. "Units" can thus be regarded as user-specified units such as µm, mm, inch, angular degrees or revolutions.

• Position

• A target position thus results directly from the number of units specified

• Speed

• The speed is standardized to "units"

• Acceleration and deceleration

• The acceleration and deceleration are standardized to "units"

Example 1:

A motor drives a toothed belt pulley directly. A boring unit is coupled 1:1 via a toothed belt. You want a resolution of 0.0001 U (= 1 unit). To achieve a speed of 900 min^-1, a value of 150 000 must be entered

Gear unit factor = 10000 – 1000 = 10000000

Example 2:

A motor drives a spindle directly with a pitch of 20 mm/revolution. You want a resolution of 10 µm (= 1 unit). To travel a distance of 7000 µm, the value 7000 (relative to the previous position) can be entered directly.

Gear unit factor = 20000 – 1000 = 20000000
