How to control the drive through the I/O interface
The table below instructs how to operate the drive through the digital and analogue
inputs when:
• the motor start-up is performed, and
• the default (Crane) parameter settings are valid.
PRELIMINARY SETTINGS
Ensure the Crane macro is active. See parameter 99.02 .
The crane is normally operated in both the forward and reverse direction
and therefore the default setting of the parameter
10.03 is REQUEST.
Ensure that the control connections are wired according to the
connection diagram given for the Crane macro.
See chapter Application
macros, control location
EXT1/EXT2
.
Ensure that the drive is in external control. Press the LOC/REM key to
switch between external and local control.
In External control, there is
no L visible on the first row
of the panel display.
STARTING IN FORWARD DIRECTION AND CONTROLLING THE SPEED OF THE MOTOR
Start in the forward direction by switching the digital input DI1 ON. DI2
should be OFF.
Note: The default setting for forward direction start digital input is DI1
and reverse direction start digital input is DI2.
1 -> 0.0 rpm I
FREQ 0.00 Hz
CURRENT 0.00 A
POWER 0.00 %
Regulate the speed by adjusting the voltage of the analogue input AI1.
1 -> 500.0 rpm I
FREQ 16.66 Hz
CURRENT 12.66 A
POWER 8.33 %
STARTING IN REVERSE DIRECTION AND CONTROLLING THE SPEED OF THE MOTOR
Start in the reverse direction by switching the digital input DI2 ON. DI1
should be OFF.
Note: The default setting for reverse direction start digital input is DI2
and forward direction start digital input is DI1.
1 <- 0.0 rpm I
FREQ 0.00 Hz
CURRENT 0.00 A
POWER 0.00 %
Regulate the speed by adjusting the voltage of the analogue input AI1.
1 <- 500.0 rpm I
FREQ 16.66 Hz
CURRENT 12.66 A
POWER 8.33 %
STOPPING THE MOTOR
Switch OFF digital input DI1 if in forward condition, or DI2 if in reverse
condition.
1 -> 500.0 rpm O
FREQ 0.00 Hz
CURRENT 0.00 A
POWER 0.00 %
