'0' Base Protocol ('I','9' response message without additional information)
'1' Extended Protocol ('I','9' response message with additional information)
Data Information Type :
Sets up of the type of information transmitted in data bytes 1 and 2:
Lift Controller Data Bytes Drive Controller Data Bytes
'0' Remaining distance using 15 bit mode
Braking distance using 15-bit mode and Extended Status of the drive controller are
transmitted alternately
'1' Remaining distance using 15 bit mode Braking Distance using 15 bit mode
'2' Remaining distance using 15 bit mode Extended Status of the drive controller
'3' Remaining distance using 16 bit mode Braking Distance using 16 bit mode
'4' Remaining distance using 16 bit mode Extended Status of the drive controller
If no ('I' '1') message is transmitted by the lift controller, the data-information-type will be set to '0' on both
controllers.
Response Data-Information-Type Message from Drive Controller
If the drive controller receives a base protocol request or does not support the extended protocol, it responds with
the message:
STX 1C 'I' '1' ETX
If the drive controller receives the extended protocol request and does support the extended protocol, it responds
with the message:
STX 1C 'I' '1' '1' ETX
Switching Function ('I' '2')
This message is used to realize advanced functions.
Switching Function Message from Lift Controller
To activate the designated function, the data byte 'switching function' is used.
STX 1C 'I' '2' Reserve Switching Function ETX
Switching Function :
'0' No function selected or function reset
'1' Activate function "Maximum Torque". The next (but only the next) travel is executed with maximum drive
torque
'R' Function 'Inverter Fault Reset' is executed
Function "Maximum torque" :
After activating the function "Maximum Torque", the torque limitation in the drive is set to the maximum possible
level during the next travel. After the next stop, the drive switches back to the previous torque limit. This allows a
monitoring of rope slip or traction ability.
Response to Switching Function Message from Drive Controller
If the message type is supported by the drive, it responds with the message:
STX 1C 'I' '2' Reserve Switching Function ETX
Switching Function :
‘
0' No function in accordance to the message ('I' '2') is active
'1' The function "Maximum Torque" is active
'R' Command 'Inverter Fault Reset' is executed
The torque limits for all quadrants [L7-01 to L7-04] are temporarily opened to 300%. After the next stop, the
drive switches back to the previously set torque limitation (parameter settings).
Date/Time ('I' '3')
The lift controller can transmit the current time and date to the drive controller. This can be used by drive
controllers without a real-time clock to synchronize their calculated clock. This information is not used in
L1000A.
