Safety system
Profibus and DeviceNet versions includes an autonomous safety system
for the door switch, disconnecting the power suply to the motors through
the safety relay and main contactors.
For Profisafe versions the door switch and emergency switch are connect-
ed to safety inputs of the communication interface. Main contactors are
connected to safety outputs of the communication interface.
For Profibus and DeviceNet versions the conductors of emergency switch
is connected to a terminal group. This terminal group is integrated into the
line global emergency stop safety system by integrator.
The red knob of emergency switch is delivered in plastic bag as the eleva-
tor emergency switch functionality is not guaranteed before it is appropri-
ately integrated into the line's safety system by the integrator.
Drives
The horizontal drive is with fixed speed controlled by a device including
contactor and motor protection.
The vertical drive is frequency controlled by a frequency converter placed
on the motor itself.
For standard versions the motor control is discrete: On/Off, Up/Down, High
speed/Low speed. Speeds are preset in hardware of motor.
For advanced versions a second communication interface provides ad-
vanced control of the motor. Speed and ramp times can be controlled by
software in Line controller. Motor current value and error codes can be pro-
vided by the motor to the Line controller.
