Operation and application
To set some motor related parameters, like motor type, rated current, motor polarity,
rated rotation speed and so on according to motor nameplate.
To set the related parameters of resolver encoder. F3.47~F3.50.
To set the control mode (F0.01=2) as closed-loop control mode
Waiting for the rotary tuning completed.
Note:
The internal driver rated slip is calculated from the synchronous speed of the motor
(120*f/P)-rated rotation speed, so the set rated rotation speed should be lower than
motor synchronous rotation speed.
A part of drivers of SINAMICS V50 can share DC common bus, please to contact our
technic support engineer if you want to share DC common bus. While sharing bus,
the master driver is АС-in and AC-out, connect the DC bus of the slaver driver to the
DC bus of the master. Warning! Usually, the power of the slaver driver can 't be more
than the 15% of the power of the master driver because the rectifier and capacitor's
capacity limitation of the master driver
When there is no Z signal in the encoder of asynchronous motor, the encoder pulse
can be set and run to 50Hz with an open loop to check the motor rotation speed and
the running direction of encoder and motor. (F3.62=0 means same direction.
F3.62=1 means that the direction between encoder and motor is reverse, you can set
F3.16 or exchange the A/В wires to make it reverse.)
As to the 24V differential PG option, when the encoder is non-differential, it can
short connect the PG option terminals 24V,A+,B+, and the encoder terminals, А/ В/
Power/ Ground, should be accordingly connected to PG option's terminals, А-/ В-
/24V/COM (or short connect PG option's terminals, СОМ/А-/ B- , and encoder
terminals, А/ В/ Power/ Ground, short connect to PG card terminals A+, B+,24V, COM,
which is mainly determined by the type of encoder.
