• Supply voltages above 56 VDC, or wrong polarity will destroy the unit. • Note that the necessary output current is depending on the load torque. Yet, the output current limits of the ESCON Module 50/4 EC-S are as follows; continuous max. 4 A / short-time (acceleration) max. 12 A.
Motherboard Design Guide Motherboard Design Guide The following provides helpful information on integrating the ESCON Module 50/4 EC-S on a printed cir- cuit board. The «Motherboard Design Guide» contains recommendations for the layout of the mother- board and specifies external components that may be required, pin assignments, and connection exam- ples.
(C1) APACITOR The function of the ESCON Module 50/4 EC-S does not necessarily require the use of an external capacitor (C1). To further reduce voltage ripple and feedback currents, an electrolytic capacitor can be connected to the voltage supply cable.
5.1.3 Motor Cables / Motor Chokes The ESCON Module 50/4 EC-S is not equipped with internal motor chokes. The majority of motors and applications do not require additional chokes. However, in the case of high supply voltage with very low terminal inductance, the ripple of the motor current can reach an unacceptably high value.
5.2.1 Ground All ground connections (GND) should be internally connected to the ESCON Module 50/4 EC-S (equal potential). It is customary to equip the motherboard with a ground plane. All ground connections should be connected to the voltage supply ground via wide conductive tracks.
All required connections are already in place and designed as screw-type terminals. Figure 5-19 ESCON Module MoBo (left), with mounted ESCON Module 50/4 EC-S (right) Figure 5-20 ESCON Module MoBo – Dimensional Drawing [mm]...
