Encoders are connected to X8 (15−pole Sub−D socket).
To avoid interference injection, only use shielded motor and encoder cables if an encoder
is used.
ƒ
Absolute and incremental encoders are supported:
– Sin/cos encoders 1 V
ss
(incremental)
– SinCos absolute value encoder 1 V
ss
with Hiperface® protocol
ƒ
Sin/cos absolute value encoders are read out by default during initialisation
(switch−on of the supply voltage). Then, the sin/cos signals are evaluated.
ƒ
Open−circuit monitoring:
– Sin/cos encoders: Comparison of the sin/cos signals and the sine−wave form
(radius monitoring)
