2.3 Mechanical Specification
(unit: mm [1inch=25.4mm])
Figure 1: Mechanical specifications
* Side mounting recommended for better heat dissipation
2.4 Elimination of Heating
EM522-CAN reliable working temperature should be < 60
℃
(140°F) and stepper motor should be <120
℃
(248°F)
It is recommended to use automatic idle-current mode to reduce drive and motor heating. That means output current will
be reduce to 50% when the motor at standstill.
It is recommended to mount the drive vertically to maximize heat sink area. Use forced cooling method to cool if
necessary.
3. Connection Pin Assignment & DIP Switch & LED Indication
The EM522-CAN has three connector blocks P1&P2&P3 (see above picture). P1 is for IO signals connections, P2 is for
power and motor connections, and P3 is for CAN communication connection. The following tables are brief descriptions of
the two connectors. More detailed descriptions of the pins and related issues are presented in section 4, 5, 9.
