2.1.2 Relay output signal
The relay output contact points on the terminal board have load capacity: 10A/250VAC and 10A/30VDC,
which can control 220V AC load of low power. If high power load is needed, a contactor can be used.
Please see Fig. 2-5.

2.1.3 Differential output signal
Differential signal refers to two equivalent signals with opposite phases sent by driving end, and the
voltage difference of these two signals is used for deciding whether the logical status of differential signal
is “0” or “1”.
Pulse command format of controlling driver motion is pulse + direction, negative logic. And this signal
adopts differential signal transmission mode.
2.1.4 Analog output signal
SVC is controllable voltage output of 0~10V and externally connected with analog voltage frequency
command inputs of inverter. Therefore altering the controllable voltage leads to inverter frequency
change and a change of inverter frequency will change the spindle speed.
