Connecting the drive to the controller
The drive is connected to a Quin motion controller using usually two multicore cables
and two discrete wire leads: one cable carries the analogue speed demand to the drive,
and the other returns the position feedback as processed in the drive. A pair of leads
connects the command to enable the drive
The analogue speed command uses a 2-core screened cable. The controller’s command
output for the chosen axis is connected to P10.3, with its 0 volts return to P10.4 and the
screen of the cable to P10.1 - refer to table 8. A suitable screened cable is RS part
number 367-325.
The encoder simulation output of the drive is connected to a Quin controller as per table
5 and figure 5, using the appropriate axis socket. The chosen axis parameters are to be
set for Quadrature x 4 encoder, which is usually the default setting.
The axis enable relay output (“normally open” and “common” pins) is connected across
P12.3 and P12.4, as per table 8: by default, the drive sources the 24 volts which is
switched by the relay. If an external 24 volts is to be used (maybe to enable a quicker
safety stopping), enable the “valid” opto isolator by removing backplane J2 links 1-2
and 3-4, then wire as per the PTS or TRC Installation Manual “typical example”.
