1 SINCOS Stepper Motor Power Stage
SINCOS is a linear stepper motor power stage particularly developed for applications
which require very high step resolution, such as: measuring tables, machine tools, graphic
instruments, etc.
SINCOS is specially recommended for applications where chopping is not acceptable.
• Designed to drive 2-phase, 8, 6 or 4 lead stepper motors
• Resolution up to 10,000 steps/rev. (for a 500-step motor)
• Front panel or external setting of step resolution and current shape
• Drive and stop currents are continuously adjustable independently of one another
• Overheat monitoring with safety cut-out and LED display
• Voltage monitoring with LED display
• No stabilized power supply required
• Compact Europe size plug-in board (100 * 160 mm)

1.1 Step Resolution/Current Shapes
SINCOS enables 15 different operating modes: Six step resolutions from full step up to
1/20 step and four different current shapes. So you can always select an adapted
operating mode for each motor type and application.
The operating mode can be set with the selector switch at the front panel.
For external programming the SELECT inputs can be used.

1.2 Motor Currents
Drive current and stop current are adjustable in a range from 0 to 100 % of the maximum
current.
The maximum current for each phase is 2.5 A (cooled), or 1.5 A (without cooling).
1.3 LED Display
Green LED +VB/ –VB
SINCOS requires a dual power supply of maximum 21V / 5A. The green LEDs show that
both supply voltages are OK.
Red LED > 85 °C
The power stage is short-circuit proof. A temperature monitoring circuit cuts off the current
if the heat sink temperature is above 85 °C. This will be displayed by the red front panel
LED. An error output will also be set.
When the temperature falls below 75 °C the unit can be reactivated by RESET.
Alternatively the supply voltage can be switched OFF and ON again. This automatically
generates a RESET signal.
