So Im wondering if the ezb4 will have a command for pulse output. I need 5vdc pulses to the tune of some 20,000 pulses. Less pulses , less travel. More pulses ,more travel. Im not concerned about resolution. Or would I need to write a script and loop the script the required amount of times for the required amount of travel. Will the EZB 4 put out 5vdc out of any of its ports? I will be powering everything from 1 sla battey 12vdc. I think I read that the ezb4 will only put out the same voltage as applied to the input side (12vdc). Thanks Chris

1. If the ez-b v4 is supplied by a 12VDC sla battery what will the voltage of the ez-b v4 signal pins be?
2. Instead of the normal ez-b pulse width modulation can the ez-b be made to output a pulses? It sounds like he is looking to control some kind of stepper as he says " less pulses - less travel".
For sure you can generate pulse using a script. There are examples in the forum of controlling stepper motors with the ez-b through scripts. I don't know about generating a frequency controlled signal using the ez-b with any accuracy.
Re: pulses. Are describing PWM? If so, yes, the EZ-B can transmit pwm. If something else, your idea of scripting pulses would probably work, but I'll let someone from EZ Robot confirm.
Opto-coupler input with 440 Ohm resistance (5 to 15 mA input current),
Logic Low is input pulled to 0.8 VDC or less, Logic High is input 4 VDC or
Pulse Signal Motor steps on falling edge of pulse and minimum pulse width
is 0.5 microseconds
Signal Needs to change at least 2 microseconds before a step pulse is sent
Enable Signal Logic 1 will disable current to the motor
(current is enabled with no hook-up or logic 0)
I will not be using the enable signal. Thanks Chris
STEPPER DRIVE 3.5A 12-42VDC 2-PH BIPOLAR MICROSTEPPING
SureStep microstepping drive, 3.5A per phase, 2-phase bipolar PWM controlled current, 12-42 VDC powered, optically isolated digital inputs for Step, Direction, and Enable. 1/2, 1/5, 1/10, and 1/50 step modes, 0.4-3.5A/phase, idle current cutback, and test mode are all dipswitch selectable (no software required).
I cant seem to link manual so this is its description, it is found at automationdirect.com. I already own the unit from a different project. Just want to clarify it will work with my new ezb4. Thanks Chris
