| SynqNet™
Digital PWM Brushless Amplifiers Features & Options |
| •
100% SynqNet™ compliant |
Allows
complete drive configuration, control, monitoring and firmware updates
over the SynqNet™ network. Synchronizes to SynqNet™
network update to minimize update jitter and skew for improved motion
control. |
| •
Digitally current loops |
Current
loop bandwidths up to 3 kHz. |
| •
Digitally tuned |
All
parameters set digitally. No potentiometers to adjust. DSP control
for the ultimate in high performance. |
| •
Silent operation |
24
kHz PWM standard. |
| •
Complete isolation |
Complete
optical isolation between signal and power stage. |
| •
Wide operating voltage |
24-370
VDC for Amplifier modules. All stand-alone and multi-axis versions
can be ordered for operation from either 110-130 VAC or 208-240
VAC (single or 3-phase, 50/60 Hz). |
| • Direct
AC operation |
No
transformer required for stand-alone units or multi-axis chassis.
Most stand-alone units and all multi-axis chassis include a DC bus
power supply, regen clamp with dumping resistor, in-rush current
limiting protection at power-on and cooling fans. Note: A reduced
cost stand-alone version is offered which does not include the regen
circuit or cooling fans. |
| •
Fault protection |
Short
from output to output, short from output to ground, amplifier RMS
over current, amplifier under/over voltage, amplifier over temperature,
motor over temperature, primary and auxiliary encoder broken wire. |
| •
RS-232 |
High
speed (115.2K baud) serial communication interface for set-up and
tuning. |
| •
Software Configurable |
Glentek’s
Windows™ based MotionMaestro™ software provides ease of
set-up and tuning with no previous programming experience required.
This software is Windows™ 95/98/2000 and NT compatible. Configuration
can also be performed over SynqNet™. |
| •
Non-volatile memory |
All
parameters are stored in non-volatile memory. Up to two configurations
can be stored at one time. |
| •
Dedicated optical inputs |
+/-
limits, node disable, home and motor over temp(non-isolated). |
| •
Dedicated optical outputs |
Node
alarm and brake. |
| •
General purpose inputs |
2
optically isolated and 2 high-speed differential receivers. |
| •
General purpose outputs |
2
optically isolated and 2 high-speed differential transmitters. |
| • Encoder
feedback |
Accepts
encoder signals up to 4.3 Mhz. Accepts traditional and reduced wire
encoders (Tamagawa, Sanyo Denki and Yaskawa). |
| •
Power on phase finding |
Eliminates
the requirement for Hall sensor/commutation tracks for many applications. |
| •
Auxiliary encoder inputs |
A,
B and index channels passed to the controller. |
| •
Status indicator |
7-segment
display indicates amplifier status and fault codes. |
| • Sine encoder interpolation |
Accepts 1 Vpp sine/cosine feedback, and interpolates
up to 4096 (12 bit). Max. frequency 500KHz/ channel. |
| • External
logic supply input (SMC9XX models only) |
24
to 48VDC, 600mA min @ 24VDC Powers all amplifier logic and encoders. |
| •
DBN |
Divide-by-N,
See page 55 for detail specification. |
| •
Sinusoidal commutation |
For the ultimate in efficiency and
smooth motion. Commutates from almost any resolution rotary encoder
or linear scale. |
| •
SMT construction |
Provides ultra compact size,
cost competitive package and high reliability. |
| •
CE compliant |
All
servo amplifiers are CE marked. |
The
difference between SMB and SMC models.
1. SMB model uses BUS input to power up the logic board and
encoder.
Advantage: Only requires one input power source to operate
the amplifier.Disadvantage:
In case of input power failure, the amplifier will shut down
completely including the logic board and encoder.
2. SMC model requires external 24VDC input to power up the
logic board and encoder.
Advantage: As long as the external 24VDC stays on, the logic
board and enconder power will stay alive even if the BUS input
shuts down.
Disadvantage:
Needs two separate input power sources (external 24VDC and
BUS input) to operate the amplifier.
