Incremental Ttl Encoder Interface X3A Subd - KEB COMBIVERT F5 Reference Manual

TTL Incremental SubD - Encoder Connections
3.3.8 Incremental TTL
Encoder Interface X3A
SubD
72
Connect the incremental encoder mounted on the motor to the 15-pin
Sub-D connector at X3A. This connection provides speed feedback and is
imperative to the proper operation of the F5.
Encoder Card Part Number: Housing Size ≤ E, 1MF5K81-DZ19. Housing
Size ≥ G 2MF5K81-DZ19.
ONLY when the inverter is switched off and the voltage

supply is disconnected may the feedback connectors be
removed or connected!

an unregulated supply and will allow up
to 170 mA max. current draw, for X3A and
X3B total. If higher voltages/currents are
required, then an external power supply
must be provided.
The +5.2 V is a regulated voltage supply
generated from V and will allow up to
var
500 mA max. current draw, for X3A and
X3B total. If additional current is required
from the +5.2 V output, the current from
V decreases in accordance with the
var
following formula:
5.2 V x I
I = 170 mA - –————

The following specifications apply to encoder interface X3A and X3B, channel 1
and 2, respectively:
• Max. operating frequency:
• Internal terminating resistance:
• RS422 or TTL level square wave
