How to parameterise the incremental TTL or SinCos encoder:
1. As encoder type ( C00422 ), select "0: Incremental encoder (TTL)" or "1: Sin/Cos encoder"
(depending on the type of the connected encoder).
2. Adapt supply voltage ( C00421 ) depending on the cable length if required (see the following
section " Voltage setting as a function of the cable length ").
3. Set encoder increment ( C00420/3 ).
4. Adjust filter time of the actual speed value ( C00497/3 ) if necessary.
• Lenze setting: 1 ms
• Lenze recommend a filter time between 1 ... 2 ms.
5. If you use the encoder as motor encoder and synchronous motor:
Carry out Pole position identification (PPI) . ( 358)
6. For detecting and monitoring the motor temperature via the Encoder cable:
Parameterise Motor temperature monitoring (KTY) via encoder . ( 375)
7. Optional: Parameterise Resolver/multi-encoder open-circuit monitoring . ( 369)
In the Lenze setting, the resolver cable and/or encoder cable are monitored with regard to
open circuit as a function of the selected speed and position encoder.
8. For a permanent acceptance of the parameter settings:
Save parameter set.
Voltage setting as a function of the cable length
The following table shows the settings required for different incremental encoder types as a
function of the cable length. The given values apply when Lenze system cables are used at typical
ambient temperatures. Other cables, cable cross-sections or extreme ambient temperatures may
require metrologically detected adaptations.
