Operation / Getting Started
Velocity Monitor Output ThevelocitymonitoroutputpinisavailableonAZBEandAZBH
drivemodelsonly.Thispinprovidesananalogvoltageoutputthatisproportionaltotheactual
motorspeed.

Tachometer Input ForAZBEandAZBHdrivemodels,whenthedriveissettoTachometer
VelocitymodebyDIP‐switchsetting,theVelocityMonitorOutputpinisusedasaDC
TachometerInput.ThedrivemustbeinTachometerVelocityModeinordertoproperlyusethe
tachometerinput.Themaximuminputallowedatthetachometerinputpinis±60VDC.
Initial Setup
Carefullyfollowthegroundingandwiringinstructionsinthepreviouschapterstomakesure
yoursystemissafelyandproperlysetup.Forinitialtestingpurposes,itisnotnecessarytouse
acontrollertoprovideacommandinput,ortohaveanyloadattachedtothemotor.Theitems
requiredwillbe:
• AZServoDriveattachedtoMountingCardorPCBInterface
• Motor
• DCPowerSupplyforsupplyingpowertosystem
• DigitalMultimeter(orohmmeterandvoltmeter)
Current (Torque) Mode Test
Initially,theAZdriveshouldbeplacedinCurrent(Torque)Mode.Bydefault,allAZdrivesare
shippedalreadysetforCurrent(Torque)Mode.However,AZBEandAZBHdriveshavethe
optionofusingDIPswitchestoconfigurethedriveforothermodes.IfusinganAZBEorAZBH
drivemodel,checktheDIPswitchconfigurationtobecertainthedriveisinCurrent(Torque)
Mode.Modeconfigurationtablescanbefoundonthedrivedatasheet.
When using a DC Tachometer in Tac
hometer Velocity mode, the
velocity monitor output function is inactive.
