Yaskawa Z1000 AC Drive HVAC - Manual (Page 72)

<4> This figure illustrates an example of a sequence input to S1 through S7 using a non-powered relay or an NPN transistor. Install
the wire link between terminals SC-SP for Sink mode, between SC-SN for Source mode, or leave the link out for external power
supply. Never short terminals SP and SN, as it will damage the drive.
<5> This voltage source supplies a maximum current of 150 mA.
<6> The maximum output current capacity for the +V terminal on the control circuit is 20 mA. Never short terminals +V and AC, as
it can cause erroneous operation or damage the drive.
<7> Set jumper S1 to select between a voltage or current input signal to terminal A2. The default setting is for voltage input.
<8> Set DIP switch S2 to the ON position to enable the termination resistor in the last drive in a MEMOBUS/Modbus network.
<9> Monitor outputs work with devices such as analog frequency meters, ammeters, voltmeters, and wattmeters. They are not
intended for use as a feedback-type signal.
<10> Use jumper S5 to select between voltage or current output signals at terminals AM and FM. Set parameters H4-07 and H4-08
accordingly.
<11> Self-cooling motors do not require the same wiring necessary for motors with cooling fans.
