connect CL86T to 7i96s

Good afternoon,

after doing some research I found this topic to be the only one containing (for me important) information on how to connect CL86T to 7i96s.

As a non-English speaker I have a lot of trouble to understand manuals especially those in Chinese-English. That is why I would like to know which pin of CL86T to connect with which pin of 7i96s.

• All pin names are CL86T on the left and 7i96s on the right, if not other specified
• I assume that DIR+ / DIR+,
• and DIR- / DIR- need to be connected
• From above linked topic i found that ALM- is being connected to GND

So I have left these pins on CL86T:
PUL+&- (what is that for?)
ENA+&- (what is that for?)
BRK/PEND+&- (as far as I understand the brake. Because I do not have a brake in my closed loop stepperdriver, I assume I don't need them)
ALM+ (the alarm positive which needs to be connected too... somewhere...)

These pins are left on 7i96s:
+5v (do I need that?)
STEP+&-

Manuals for both are attached.

Another related question: what cables in mm2 are you using and how long should they be?

Thanks for your help

CL86 7I96
PUL+ +5V
DIR+ +5V
PUL- STEP-
DIR- DIR-

( Optional ) Alarm wiring depends on how you have your isolated input common
connected and whether you want an individual (per axis) or common alarm.

For step/dir signals I buy ethernet cable and cut it to length.

I use 22AWG shielded/stranded.

Two twisted pairs get connected to the complimentary pair on the drive (STP+/STP-, DIR+/DIR-)

The other two pairs can be used for drive alarm and enable, or a second drive's step/dir if the drives are really close together.

Shield drains connected to ground point as close to 7i96s as possible.

"PUL" is the same as "step" (means 'pulse')

ENA is an enable signal.  If you choose to use this feature, you can enable/disable the drive without just cutting all power to the main DC bus.  If a drive is disabled the motor will not be trying to hold position and you can rotate it by hand.

PEND is an 'on-position' signal.  If the drive receives a command to move a certain number of steps, when it is finished moving the PEND signal is triggered.  Not really useful for LCNC, but used extensively in automation with PLC's and motion logic when the stepper motor movement is part of a sequence.
