Programming Parameters

C-39

Name: Acc_Scale_Type

Data Display: Bit Pattern

R/W

Parameter No.
160
File:
Control
Group:
Acceleration

Description: Acceleration data scaling type. A variety of scaling methods can be selected by means of the
acceleration data scaling type parameter. This parameter is used with SERCOS interface. For the analog
configuration see parameter 260.

Enumerated Bit Pattern:
Structure of the acceleration data scaling type:
Bits 2–0: Scaling method
000 – no scaling
001 – linear scaling
010 – rotational scaling
Bit 3:

0 – preferred scaling
1 – parameter scaling

Bit 4: Units for linear scaling

0 – meters (m)
1 – inches (in)

Bit 4: Units for rotational scaling

0 – radian (rad)
1 – (reserved)

Bit 5: Time units

0 – seconds (s)
1 – (reserved)

Bit 6: Data reference

0 – at the motor shaft
1 – at the load

(all other bits are reserved)
