Analog
Brushless Amplifiers Features and Options
|
| •
Ergonomic design |
Easy
access to connections, adjustments and test points. |
| •
SMT construction |
Provides
ultra compact size, cost competitive package and high reliability. |
| •
Silent operation |
20 kHz PWM (Pulse Width Modulation) standard. |
| •
Complete isolation |
Complete
optical isolation between signal and power stage. |
| •
Multimode operation |
The
Trapezoidal and 2-Phase/3-Phase Current Mode servo amplifiers can
operate in current (torque) mode and the Resolver Based Sinusoidal
servo amplifiers can operate in either current (torque) or velocity
(RPM) mode. |
| •
Wide operating voltage |
Operating
voltages range from either 70-240 or 240-340 VDC for Module and
3U Plug-In configurations and either 110-130 VAC or 208-240 VAC
for Stand Alone and Multi-Axis configurations. |
| •
Direct AC operation |
No
transformer required for stand-alone units or multi-axis chassis.
The stand-alone units and multi-axis chassis include DC bus power
supply, regen clamp and dumping resistor, in-rush current limiting
protection at power-on and cooling fans. |
| •
Three basic versions |
Available
in Trapezoidal, 2-Phase/3-Phase Current Mode and Resolver Based
Sinusoidal commutated versions. |
| •
Fault protection |
Short
from output to output, short from output to ground, amplifier RMS
over current, amplifier over voltage and amplifier over temperature. |
| •
Industry std. mounting |
Available
in Module, Stand Alone, Multi-Axis and 3U Plug-In configurations.
Optional custom mounting configurations are available to meet virtually
any requirement. |
| •
LED status indicators |
A
green LED illuminates to display normal operating conditions while
red LED’s illuminate or flash to indicate various faults. |
| •
Dedicated inputs |
+/-
limits, inhibit, fault, motor over temperature and reset. |
| •
External fault reset |
An
input is provided to reset the amplifier in the event of a fault. |
| •
Current limit |
Peak
motor current is adjustable. |
| •
Bandwidth |
All
servo amplifiers have a maximum 3000 Hertz current loop bandwidth
which varies with the motor inductance. |
| •
CE compliant |
All
servo amplifiers are CE marked. |
