Page 4: General Information
User manual AD CM M Page 4 of 20 General Information 1.1 Product Description The main interest of the use of a current mode driver such as the AD CM models is the current control independent from the supply voltage (chopper). This allows to apply a much higher voltage than needed to drive the current without risk of overheat. -
Page 5: Available Versions
User manual AD CM M Page 5 of 20 1.1.1 Available versions The AD CM M_S is available in three different versions AD CM M1S (Standard stock item) Basic driver, requiring only clock and direction signals, it is destined to be controlled by a PC or any other host. -

User manual AD CM M Page 9 of 20 Set-up and installation of AD CM M1S This section refers to all functions offered by the stepper motor driver type AD CM M1S. The set-up of the M2S and M3S version is the same, relatively to the functions of the M1S, but offers some additional functionalities. 2.1 Block Diagram Host Translator... -
Page 10: Command Connector
User manual AD CM M Page 10 of 20 Note Both M2S and M3S versions can be used as M1S version if the jumpers ADJ, VCO and CK on the mezzanine board are removed (see section 3 and 4 for more information about the jumpers). 2.3.1 COMMAND connector Input voltage for all inputs varies from 5 to 24VDC This 12-pins connector is available on all driver versions, it provides access to all functionality. - Page 11 User manual AD CM M Page 11 of 20 PIN3 Direction of rotation The signal can be changed at any time but it takes effect after the next following clock pulse. If the clock and direction signals are triggered at the same time, the step execution will change immediately. Warning: As PIN1 to 3 are high-active inputs, the switches for operation mode (see section 2.3.2) must all be in the OFF position so that they can be activated.

Page 12: Switch For Operation Mode
User manual AD CM M Page 12 of 20 HOME is a function needed to know the commutation position of the driver. It is activated every time Phase A of the motor is energized with positive current. This helps to home the clock of the host to the driver commutation, a function helpful to avoid step losses when power to the driver is lost. -

Position B The external Analogue Speed Reference input is used (PIN 12 on COMMAND connector). -
Page 20: Special Notes
User manual AD CM M Page 20 of 20 Special NOTES 5.1 Pull-up resistor Pull-Up The inputs of the drivers namely clock, direction, START/ STOP are open collector inputs. Open Collector (or Open Drain) output is frequently offered by programmable logics because of their higher safety. They require an adaptation to the AD driver series with a PULL-UP resistor.
