Parameters Description
NOTE!
When the speed reference control is programmed for communication networks (P1023 = 7), then the
digital input DI2 does not have a specific function for the crane horizontal motion applicative
P0265 – DI3 Function
Adjustable 0 to 31 / 0 = Not Used
Range: 2 = Coast to Stop
3 = Fast Stop
21 = Emergency Stop (PLC Use)
Proprieties:
Access groups via HMI:
Description:
This parameter defines that the function of the digital input DI3 will be stopping the operation of the crane
horizontal motion.
■
Not Used: It defines that no operation stopping command for the crane horizontal motion will be executed.
■
Coast to Stop (General Enable): It defines that the crane horizontal motion operation stopping will be by motor
coasting (the motor is demagnetized).
With logical level "0", it executes the stopping command by coasting, not exercising any control to decelerate
the crane horizontal motion motor, so that the motor coasts to stop and remains demagnetized. The alarm
"A752, Coast to Stop" is generated until the digital input DI3 is activated with level "1".
With logical level "1", it indicates that the crane horizontal motion is enabled, so that a command for load
forward or load reverse can be executed.
■
Fast stop: It defines that the stopping operation will be carried out with a null deceleration ramp, so that the
motor is decelerated down to zero rpm in the shortest possible time.
With logical level "0", it executes the fast stop command with null deceleration ramp, so that the crane horizontal
motion motor stops in the shortest possible time. The alarm "A754: Fast Stop" is generated until the digital input
DI3 is activated with level "1".
With logical level "1", it indicates that the crane horizontal motion is enabled, so that a command for load
forward or load reverse can be executed.
■
Emergency Stop: It defines that the stopping operation will occur according to the deceleration ramp that has
been programmed in P0103.
With logical level "0", it executes the emergency stop command by decelerating the crane horizontal motion
motor according to the deceleration ramp that has been programmed in P0103. The alarm "A756: Emergency
Stop" is generated until the digital input DI3 is activated with level "1".
With logical level "1", it indicates that the crane horizontal motion is enabled, so that a command for load
forward or load reverse can be executed.
NOTE!
This command overrides the load forward or load reverse command, stopping the crane horizontal
motion and preventing the execution of a new command.
