Figure 9 Connecting an 8-lead stepper motor in parallel connection
!
Warning
Never connect or disconnect a stepper motor while the power is on.
Connecting an E-Stop Switch or Shorting the Connection
The E-Stop connection is required.
The E-Stop connector is located next to the power connector (Figure 3). By
default, the MX4660’s activation requires an emergency stop switch connected, or having the two connection
pins, “ESTOP+” and “ESTOP-“, shorted.
Refer to Figure 10 for how to connect an” E-Stop switch. To short the E-Stop connection, just connect a signal
wire between the “ESTOP+” and “ESTOP –” pins.

!
Notice
Without the a E-STOP switch connected, or short circuit between Estop+ and Estop-
pins, the red LED lights of the 4 stepper drive modules will blink 3 times periodically
when MX4660 is powered on
Enabling / Disabling Charge Pump
To make MX4660 working properly, setting this switch to the right position is required.
The MX4660 is featured
with a feature called “Charge Pump”, a watchdog timer to enable/disable the MX4660. When the charge pump
feature is turned on, the MX4660’s activation will depend on the receiving of 10 KHz signals at pin 16 of the
DB25 connector. When the “Charge Pump” feature is turned off, the MX4660 will be activated without such
verification.
