• Drive Remote Display Control via lift controller
• Drive Remote Keypad Control via lift controller
• Extended data communication between lift controller and drive controller
• Idle state
All operation of the drive controller is possible by remote control mode. The display lines are transmitted and
displayed both at standstill and while traveling. After changing a parameter on the drive controller via remote
control mode, bit S0 [Drive Controller Ready] must switch off, and no further travel command needs to be
accepted.
After leaving the remote control mode without any modifications, the drive controller switches on bit S0 [Drive
Controller Ready] and is ready to travel.

assignment to the buttons:
The button "ESC/Reset" functions like "ESC" in the programming menu, and like "Reset" in the fault display. The
button "Run/Stop" issues a RUN command when not during RUN, and issues a STOP command when during
