They
cannot
be
used
simultaneously
.
If the communication mode is used
,
a communication card must be installed
.
The
VDF650 provides four optional communication cards and you can select one based
on actual requirements
.
If the communication protocol is Modbus
,
PROFIBUS
-
DP
or CANopen
,
the corresponding
serial communication
protocol needs to be selected
based
on

The
CANlink
protocol
is
always
valid

two
parameters are
used to set
the
maximum frequency
in
forward
or
reverse
rotation in
torque
control
mode
.
In torque control
,
if the load torque is smaller than the motor output torque
,
the motor
'
s
rotational speed will rise continuously
.
To avoid runaway of the mechanical system
,
the
motor
maximum
rotating
speed
must
be
limited
in
torque
control
.
You can implement continuous change of the maximum frequency in torque control
dynamically
by
controlling
the
frequency
upper
limit
.

In torque control
,
the difference between the motor output torque and the load torque
determines
the
speed
change
rate
of
the
motor
and
load
.
The
motor
rotational
speed
may
change quickly and this will
result
in noise
or too large mechanical stress
.
The setting
of
acceleration
/
deceleration time
in torque
control
makes the motor rotational
speed
change
softly
.
However
,
in
applications
requiring
rapid
torque
response
,
set
the
acceleration
/
deceleration
time
in
torque
control
to
0
.
00s
.
For
example
,
two
AC
drives
are
connected
to
drive
the
same
load
.
To balance
the
load
allocation
,
set
one AC
drive
as
master
in speed
control and the
other
as
slave
in
torque
control
.
The
slave
receives
the
master
'
s
output
torque
as
the
torque
command and must follow the master rapidly
.
In this case
,
the acceleration
/
deceleration
time
of
the
slave
in
torque
control
is
set
to
0
.
0s
.
