Prior to start-up the inverter must be adapted to the encoder(s) which is/are used.
Ec.0 displays the installed encoder interface 1; Ec.10 displays the installed encoder
interface 2. The values correspond to following interfaces:
Value Encoder interface
0 no Interface
1 Incremental encoder input TTL
2 Incremental encoder output 5 V
3 Incremental encoder input and output direct (not divisible by Ec.27;
switchable with Ec.20)
4 Incremental encoder input and output TTL (switchable with Ec.20)
5 Initiator
6 SSI Interface
7 Resolver Interface
8 Tacho
9 Incremental encoder output TTL (from resolver over channel 2)
10 Incremental encoder output TTL
11 Hiperface
12 Incremental encoder input 24 V HTL
13 Incremental encoder input TTL with error detection
14 Sin/cos encoder input
15 Incremental encoder input 24 V HTL with error detection
In case of an invalid encoder indentification the error „E.Hyb" is indicated and the
measured value in is displayed inverted in ec.0/ec.10.
On changing the encoder interface the error „E.HybC" is indicated. By writing on
parameter ec.0 or ec.10 the change is confirmed and the default values for the new
interface are loaded.
With this parameter the encoder line number is adjusted to the connected encoder
within a range of 1...16383.
• ec.1 for encoder interface 1
• ec.11 for encoder interface 2
This parameter defines the time over which the speed average is determined. At that
the resolution of the speed detection is defined simultaneously.
