8.1. Speed signal towards the motor’s controller
As standard, the electronic control lever provides 2 channel voltage output signals are reported in the
drawing here above. In case you need a different voltage profile, it must be specified when ordering.
As an alternative it is possible to interface to the motor’s controller via CANBus, in this case please refer to
the next chapter.
8.2. Programming of the delay when passing from Forward to Reverse or vice
versa
Sometimes to avoid shocks on the drive line, it is suggested to insert a delay time when inverting speed
direction. This delay does not occur when from neutral you move to forward or reverse.
Dip-switches 3 and 4
(see chapter 5) identify the delay time between forward reverse commands.

8.3. CanBUS protocol
Every CANBus interface card has one output. Communication starts automatically at power-up.
This document refers to SAE J1939 CANBus protocol. The electronic system can handle also other
communication protocols.

Data field:
The 8 bytes of the Can Data Link are completely programmable according to the profile used by the motor
producer. In the data field you must write the motor speed reference. Necessary information for majority of
the motors are
minimum speed
and
maximum speed without load
.
8.4. Technical data of the CANBus interface card
Maximum speed which each channel can generate is 100 mA. Each channel output is protected against
short circuit towards ground and towards voltage supply. Termination resistor is already mounted on the
CANBus interface card but it can be removed when ordering at factory.
