5.5.1 Resolver connection
Note!
ƒ Use the prefabricated Lenze system cables for the connection of
a resolver.
ƒ Cable length: max. 50 m
ƒ Depending on the cable length and resolver used parameterise
the code C0416 (resolver excitation amplitude).
Check the resolver control with code C0414 (recommended
values: 0.5 ... 1.2; ideal value: 1.0).
ƒ Before using a resolver from another manufacturer, please
consult Lenze.
Connect a resolver via the 9−pole Sub−D socket X7.
Features
ƒ Resolver: U = 10 V, f = 4 kHz
ƒ Resolver and resolver supply cable are monitored for open circuit (fault
message "Sd2").
