••
••
• Isolated current feedback
AC current transformers sense current in each bridge.
••
••
• Impedance-isolated armature voltage feedback
High impedance resistive voltage divider network used for arma-
ture voltage feedback.
••
••
• Tachogenerator feedback
50 volt/1000 rpm tachometers may only be used for speed
feedback.
••
••
• Dual AC line voltage
120 or 240 vac line voltages are plug selectable.
••
••
• Dual field voltage
100/50 or 200/100 volt field supplies for 120 or 240 ac line
voltages.
••
••
• Matched +12V and -12V reference supply
••
••
• Regenerative braking to zero speed with signal contact
output

1.2 Standard Features
••
••
• Power
Single phase 120 or 240 vac, 50/60 Hz., (±10%).
••
••
• Speed range
30:1 with armature feedback, 50:1 with tachometer feedback.
••
••
• Load regulation
±3% with armature voltage, (±10% line voltage change).
••
••
• Acceleration/Deceleration
Adjustable: 0.1-30 seconds from 0 to full speed.
••
••
• Temperature range
32°F - 104°F (0-40°C).
••
••
• Altitude
2000 feet (600m) maximum without derating.
••
••
• Regenerative braking
Upon application of a stop signal the drive will regeneratively
brake and stop at zero speed. This feature depends on the setting
of jumper P1 (see page 5).
