Parameter
Description Data Read/write
P148*
Pulse#Multiturn
148
Function parameter for entering the resolution of the
multiturn encoder. The resolution is indicated in bits.
Index 01: Motor encoder resolution/rev.
Index 02: Motor encoder number of revolutions
Index 03: External encoder resolution/rev. or of linear axis
Index 04: External encoder number of revolutions
Index 05: Resolution ratio opt. signal period ser. protocol
(linear scale of motor encoder) (spare), not yet supported
in V1.40.
Index 06: Resolution ratio opt. signal period resolution of
ser. protocol (linear scale of external encoder), not yet
supported in V1.40.
Index 07: Specification as exponent to base 2
Resolution ratio between signal periods and serial
protocol for motor encoder with SSI protocol.
Index 08: Specification as exponent to base 2
Resolution ratio between signal periods and serial
protocol for technology encoder with SSI protocol.
Indices 1..4:
No high-resolution encoders are permitted for the external
encoder (P148.3 <= 14).

Indices 5 to 6 (for linear scales only, not yet supported in
V1.40)!
Normalization ratio between resolution of sine/cosine
tracks and resolution (length of one increment) of the
serial protocol (see data sheet of the encoder concerned).
Example: linear scale LC181 (Heidenhain):
Signal period opt. tracks 16μm
Resolution ser. protocol 0.1μm
=> division ratio P148.6 = 160
