Yaskawa AC Drive Z1000 Bypass Technical Manual - Manual (Page 55)

<1> This voltage source supplies a maximum current of 150 mA on control board A1.
<2> 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.
<3> Use jumper S1 to select between a voltage or current input signal to terminals A1 and A2. The default setting is for voltage
input.
<4> Set DIP switch S1 to the ON position to enable the termination resistor in the last drive in a MEMOBUS/Modbus network.
<5> 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.
<6> Use jumper S5 to select between voltage or current output signals at terminals FM and AM. Set parameters H4-07 and
H4-08 accordingly.
<7> Set E1-01 and E1-05 to 208 for 208 Vac applications.
<8> Connect the cabinet ground lug to earth ground.
<9> Branch circuit protection must be supplied by the installer when no input circuit breaker option PM or when noted on the
cabinet data nameplate.
<10> Insulated twisted shielded wire is required. Connect the shield only at this end and stub and isolate the other end. Do
not run these wires in the same conduit as AC power or AC control wires.
<11> The motor overload relay is factory set for manual reset. Adjust the motor overload relay trip setting for the actual AC
motor full load amps.
<12> Secondary fuse F6 is added with control transformer T1 or a power rating 350 VA or greater.
