S
Encoder x control word Gx_STW.6 = 1
The following limitations and rules apply:
1. Which combinations of power module and control board are pos-
sible?
– 1–axis power module with 2–axis control board
In this case, drive B is not available.
– 2–axis power module with 2–axis control board
Drive B is available.
The following applies: Switch drive B into a passive state (P0700
(B) = 0)
2. Which encoder systems are available for encoder 2?
Dependent on the 2–axis board with encoder for sin/cos 1 Vpp or for
resolver, the following rotary or linear measuring systems can be
connected at X412:
– Incremental encoder with sin/cos 1 Vpp
– Absolute value encoder with EnDat protocol
– Resolvers
3. Process data for encoder 2
– Control word:
– Status words:
4. Encoder 2 is activated with P0879.12 (A) = 1.
The following applies:
– This activation becomes effective after POWER ON
– Encoder 2 must be commissioned
––> refer to the Start–up Assistant of SimoCom U
– It is not permissible to operate drive A without a motor measuring
system.
––> The following must be valid: P1027.5 (A) = 0
– Input terminal I0.B (fast input from drive B) can be assigned a
function for encoder 2 from drive A via P0672.
e.g. the "equivalent zero mark" or "flying measurement" function
