Page 10: Digital Inputs
2.2.2 Digital Inputs The drives are equipped with 4 digital inputs for the control of the functions: • Boost current BOOST • Enabling of the power stage • Step (or CLK_UP) STEP • Direction (or CLK_DWN) All digital inputs are available on CN2 connector of the drive and they can be used at voltages 2-24Vdc.
Page 11 Steps per Rotation Table: The rotation measured in degrees of the motor shaft, for every single step pulse depends on the settings of the Roto-switch R1 (refer to paragraph 3.5.2.2 Step angle). The following table shows the number of necessary step pulses to let the motor shaft execute a full rotation (360°) and the rotation in degrees executed by the motor shaft at every step pulse (the table refers to 50 poles motors, 1.8°...
Page 12 The following ﬁgures supply some examples of possible connections to the digital inputs: Voltage: 3.3 – 24 Vdc Voltage: 2 – 24 Vdc N.B. It’s recommended to use 2Vdc digital inputs only in Line-Driver conﬁguration to have more noise immunity.. For a proper use, the Digital inputs must be wired using shielded cables.

Page 20 Main characteristics of the drive power supply: AC network switch: is a recommended safety device. Primary protections: use fuses on the AC bus or an equivalent safety switch. Surge suppressors: on the primary circuit, they protect the drive against Surges coming from the primary network power supply.
Page 21 Secondary protections: must be placed before the rectiﬁer bridge and must be calibrated depending on the set phase current. Instead of the secondary protections can be used an automatic safety switch. Rectiﬁer bridge: a rectiﬁer of 15A is recommended for the maximum absorption of a single axle.

Page 26: User Configurations
3.5.2 User conﬁgurations The drives are equipped with a series of Dip-Switches with 8 contacts and two Roto-Switches with 16 positions. In factory default all DIPs are OFF, R1 is in 2 position and R2 is in 0 position. This condition set the minimum current, a standard value of the step angle and none torque ﬁlter. NOTE: the device reads the Dips and Roto-Switch R1 only during the Power up.
Page 27: Step Angle
3.5.2.2 Step angle The type of step angle could be selected by the Roto-switch R1 on 15 different levels. It possible to select step angle base “2” : 1/2, 1/4 ,1/8, 1/16, 1/32, 1/64, 1/128, 1/256 and step angle base “5” : 1/5, 1/10, 1/25, 1/50, 1/125, 1/250 and also the Full Step. The factory default is in position 2 = 1/4 step angle.
Page 28: Automatic Reduction Of The Motor Current (Rwc)
3.5.2.4 Automatic Reduction of the motor current (RWC) Allows to reduce consumption and heating of the motor and drives when is not required a movement. The motor is stopped with a reduced current manteining also a detent torque. DIP5 Default Function The motor current will be reduced to 70% of the nominal value 1 second after the last step pulse.
Page 29: Torque Filter
3.5.2.8 Torque Filter With Roto-Switch R2 is possible to set a Torque Filter in order to reduce vibrations, resonance and noise of the motor. Roto-Switch R2 position Torque ﬁlter level None (Default) ..Medium ..High NOTE : the Roto-Switches R2 is read and executed in real time. If it’s necessary a setting change, take all necessary measures to avoid possible dangerous contacts.
