M
Connect power supply that is free from interference emission. The supply must not be used as
parallel supply of drives, shields, magnetic valves, etc.
Apply DC according to the terminal assignment
Power supply: 24 VDC ±10 %
Shield
Use shielded cables only. Ground of the shield must be provided at the machine.
(two examples corresponding to the cable applied, see drawings).

* To avoid bus collisions a minimum timeout reply of 1 ms (default
parameter) is to be kept, i.e. the time elapsed between transmitting the
last bit of the query until start transmitting the 1st bit of the SPA response.
The operator should see that due to the minimized timeout reply of 1 ms
the bus switching time after having transmitted the last bit must not exceed
1 ms.
The default parameter of 1 ms can optionally be altered by serial interface
in steps of 0,1 ms within the range of 0,1 ... 60 ms. Refer to command „x“
(78h).
Timeout reply*: 0,1...60 ms
BUS switching time**: <0,1 ms
** The BUS switching time is the time the SPA requires to be ready again for
transmission receipt after having replied to host.
