z 3540MO Oscillator Joystick Mode
|
 |
accepts 12-42 VDC power supply (including ripple) |
|
switch selectable motor current: 0.4 to 3.5 amps |
|
12,800 steps/rev |
|
digital oscillator/speed controller is extremely accurate and repeatable, deriving all timing from a quartz crystal |
|
2 speeds, selectable from external signal |
|
joystick mode allows bidirectional control from 0-5V analog joystick, a switch can be used to change from high to low speed ranges for fast moves and precise positiong. |
|
on-board trimpots for all settings (one speed can be set by external pot of 0-5 volt analog signal trimmed by on-board pot) |
|
3 state MOSFET PWM amplifiers |
|
4 optically isolated 5-24 V digital inputs can be configured for sinking of sourcing logic |
|
automatic idle current reduction (defeatable) |
|
enable input (turns off current to motor windings) |
|
optically isolated Tach Out signal allows easy measurement of monitoring of speed and distance |
|
drives 4, 6 or 8 lead step motors, sizes 14-34 |
|
compact size (1.5 x 3.0 x 4.0 inches) |
|
thermal protection |
|
optional heat sink |
|
screw terminal connectors |
Description
The ampliers regulate motor current by chopping at a constant, inaudible frequency. Phase current is selected from 32 levels by a DIP switch.
The 3540 MO is a PC board mounted on an aluminum angle heat transfer chassis. Mating head sink is available for applications where the drive cannot be mounted to a heat sinking surface.
