5.2.2 Low-voltage connections
5.2.2.1 Encoder
5.2.2.1.1 Square wave encoder
Connect the incremental encoder using a shielded cable . Make sure the shield is connected to PE
firmly and as close as possible to the VVVF controller (use a metal clamp).
Make sure that the incremental encoder is connected to the VVVF controller correctly. The terminal
assignment is as follows:
Terminal

30 +5V Supply voltage for TTL encoder
31 + 15V Supply voltage for HTL encoder
66 GND Ground connection

5.2.2.1.2 Sine encoder
Connect the sine encoder to the 15-pole D-SUB socket at the front plate of the VVVF controller (to the
right of the display).
The VVVF controller must be switched off before connecting the sine
encoder !
The different operation modes are realized via the corresponding adapter circuit boards in the
converter. For a list of appropriate encoder types, refer to the following pages.
Note : Since sine encoders use relatively low signal levels, make sure to provide neat, continuous
shielding. If the encoder is bought from us, the connection cable is already ready-made. If you do not
use a ready-made encoder cable, make sure to use shielded connectors and to connect the shield
properly.
