Page 5: Sincos Stepper Motor Power Stage
Manual SINCOS 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. -
Page 6: Step Resolution/Current Shapes
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. -
Page 7: Motor Currents
1.3 LED Display Green LED +V / –V 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. -

Page 11: Principle Of Operation
Manual SINCOS 3 Principle of Operation To reach all intermediate positions between two full steps, both phase currents of a 2- phase stepper motor have to be controlled and phase-shifted by 90 degrees. This control is effected by an EPLD: By each control pulse a counter will be incremented or decrement- ed in function of the direction of rotation. - Page 12 Fig. 5: Schematic diagram Manual 2066-A006 GB...

Page 13: Inputs
Manual SINCOS 4 Inputs The inputs include internal 4.7 kΩ pull-up resistors and are designed for open collector control signals. Fig. 6: Input wiring 4.1 Control Pulses One control pulse provokes one motor step. With the falling signal edge the direction input signal is stored and the drive current switched ON. -
Page 14: Motor Stop
Fig. 7: Time diagram: control pulses and motor direction The control pulse signal width should be at least 2 µs (maximum frequency 200 kHz). The direction input must not be changed within 1 µs before and 1 µs after the falling edge of the control pulse signal (see time diagram). -
Page 15: Select A, B, C, D
Manual SINCOS 4.6 Select A, B, C, D Via four external data lines, step resolution and current shapes can be set instead of using the selection switch. For enabling setting by the inputs, the upper front panel selection switch has to be set to position F. -
Page 16: Overtemperature Output
The losses can be reduced as well as the heat sink temperature, by applying a lower supply voltage. 5 Supply Voltage The SINCOS unit requires a dual supply voltage in the ranges of –8 to –21 V and +8 to +21 V. The voltage value depends on the desired run frequency. -
Page 17: Phase Current Setting
0 to 100% of the maximum value. As the following figure shows, the true values can be measured with instruments. The SINCOS has to be set to the full step mode! Fig. 9: Phase current measuring 5.2.1 Stop Current... -

Page 19: To Consider Before Installation
By persons without proper training and qualification serious damages to devices and persons might result! 7.2 Safety Instructions 1. Check the output voltages of the supply unit before connecting the SINCOS rear connector. Inverted supply voltage leads would immediately cause damage of the power stage. -
Page 20: Warranty
Danger of injury if touching the surface ! 8 Warranty The SINCOS stepper motor power stages are subject to Phytron's legal warranty. Phytron will repair or exchange units which show a failure due to defects in material or caused by the production process. -
