3.4.7 Command Pulse Output and Connection to Drivers

The following table shows the requirements for the command pulse output circuits.

Note: When using a motor driver that is not the differential input type, be especially careful about the speed
and the cable length.
A standard is 500Kpps (cable length: 3m or shorter) for drivers with single-ended type input photocouplers,
and 250Kpps (1m) for those with TTL input. Use twisted pair wires for signal lines. Also, check the
specifications for the connection to the motor driver controller in advance.

Table 3.4-10 Command pulse output circuits
1. Output element: Differential driver (26LS31 or equivalent)
2. Command pulse width: 50% duty width of command frequency
However, in the case of 2.4Kpps or less: 200μs width
In the case of 5Mpps or above: 30% duty width
Set by G9003 initial setting (RENV1-b2 to b0)
