Hitachi L2002 manuals
Computer Equipment > Power Supply
When we buy new device such as Hitachi L2002 we often through away most of the documentation but the warranty.
Very often issues with Hitachi L2002 begin only after the warranty period ends and you may want to find how to repair it or just do some service work.
Even oftener it is hard to remember what does each function in Power Supply Hitachi L2002 is responsible for and what options to choose for expected result.
Fortunately you can find all manuals for Power Supply on our side using links below.

When the fault is cleared the alarm signal becomes inactive We must make a distinction between the alarm signal AL and the alarm relay contacts [AL0] [AL1] and [AL2]. The signal AL is a logic function, which you can assign to the open collec tor output terminals [11] or [12] or the relay interface to higher voltage and current devices (10 mA minimum) 188 Trip/Power Loss Alarm –Trip Alarm – 189 Analog Input Disconnect DetectVoltage signal loss at [O] terminal Current signal loss at [OI] terminal 190 PID Second Stage Output193 Network Detection Signal194 Logic Output Function195 C141, C142, C143196 Option Card Detection Signal197 AMH O OI LVoltage Input Current Input 198 Other Analog Input-relatedtopics:201 PID Loop ConfigurationPID Output Limit Error Inversion Other PID-relatedtopics: 202 Simultaneous ConnectionsInverter Configuration for Two Motor Types 203 Parameter Codes1st motor 2nd motor 205 Inverter SystemAccessories206 Motor ControlAccessories 207 AC Reactors, Input Side•If the unbalanced factor of the power supply is 3% or higher •If abrupt power supply changes are expected Examples of these situations include: 1.Several inverters are connected in parallel, sharing the same power bus An installed Example calculation: VRS = 205V, VST = 203V, VTR = 197V where VRS is R-Sline voltage, VST is S-Tline voltage, VTR is T-Rline voltage Unbalance factor of voltage Meanline voltage ) ⁄ ⋅ 100 205 – 1.5% AC Reactors, Output Side Control Motor 208 Zero-phaseReactor (RF Noise Filter)EMI Filter RF Noise Filter (Capacitive) DC Link Choke 209 Dynamic Braking UsageSelecting Braking Resistors for External Braking Units 210 Dynamic BrakingNote the column meanings in the tables: •Column “A” = Average braking torque from 60 Hz to 3 Hz •Column “B” = Average braking torque from 120 Hz to 3 Hz 213 Troubleshooting 6 and Maintenance229 Glossary andBibliography 237 ModBus NetworkCommunications 281 Drive ParameterSettings Tables 293 CE–EMCInstallation Guidelines 299 Index
