The Next Stage (1746-HSTP1)

Hello all,

Well I am back. I have been using and learning a lot about the SLC500 and I am able to use the Input / Out cards / Analog In / Out cards and I have done a lot. I have used the advanced HIM interface.

I would like to thank you all but now I have 1 battle where I need some help.

The 1746-HSTP1

Okay,

I have the following:

SLC500 Card - 1746-HSTP1
Stepper Motor - AXHM015K-30 (http://www.airlinehyd.com/APOLLO/ORIENTAL/AXH.PDF)
Driver - OEM750 http://www.parkermotion.com/manuals/OEM750/OEM750_Entire_Rev_B.pdf

So, I have the following, I saved up for a few months to buy this and now I need to set it up.

I understand that people can say, just go a learn. I have but, I feel that I need to approach this part with caution as I do not want to blow up anything.

Here are some of the objectives:

1. Wire up the stepper motor to the driver
2. Wire up the driver to the stepper card
3. make a simple program to step the motor

Thank you all and I really need you help with this one.

Please note, I am not working for a company, I am doing this just to expand my mind.

Thank you

Update.

Okay, the stepper motor have 8 Wires.

In order, left to right (black, purple, blue, yellow, green, orange, pink, white)

If pass 6v through:

black and purple CW
black and blue CCW

The rest, nothing, am I missing something here?

3 Wire stepper motor?

The link you provided is to a DC motor and variable speed control - NOT a stepper motor.
The part numbers in that datasheet don't match exactly with the part number you provided and the color codes are not exact (you mention blue and pink - datasheet does not have those listed).

A stepper motor would normally be 4 or 6 wire.
If you applied some voltage to the correct pins of a stepper driver you would likely only get one step, not a CW or CCW rotation.

Well, that is fantastic.

Ok. thank you danatomega. I spent all night learning about the stepper controller and driver. Okay, so I need a stepper motor.

Does anyone have 1 that can sell me in Europe.

Could I use this?

I really appreciate the support.

Thanks

Okay. Great news. I have a Stepper motor connected to the Driver - OEM750. And all is working.

I just need a littler help connect the Driver - OEM750 to the AB 1746-HSTP1

The image below show the connections for the OEM750 to the AB 1746-HSTP1

I guess I would have to supply 5v to connections 1 & 18 on the 1746-HSTP1?

Please let me know

THANK YOU!!!!!

Both the manual and your included diagram say that pin-1 get 7-24 VDC. I don't think 5VDC is going to be sufficient.

If you're trying to match the 5VDC shown on the OEM750 diagram, it shows that all the external signals are opto-isolated so you shouldn't worry about matching the voltages.

Thank You.. I have it working

GREAT... Now the next part!!!!!!!!!

I have to work out the coding required.

Thank you

Should I create a new POST?

I don't really know the rules for that, but I believe you can continue this one since it's all related to your original post...

Ok, I have an issue. I can get CW to work however CCW does not work.

This works, acceleration, and deceleration
Clock Wise
N7:10 128 - 0 - 0 - 0 - 50 - 0 - 50 - 40 - 0 - 0


This dose NOT work. The green LED does come on. So, I think it is about the wiring
Count Clock Wise
N7:10 256 - 0 - 0 - 0 - 50 - 0 - 2000 - 2000 - 0 - 0

The OEM750 & 1746-HSTP1 use the same power supply, AB PSU 24V

OEM750 - 1746-HSTP1

PIN 1 - PIN 2 (CW + or non directional pulse output)
PIN 2 - PIN 3 (CW - or non directional pulse output)
PIN 3 - PIN 4 (CCW + pulse or direction signal output)
PIN 4 - PIN 5 (CCW - pulse or direction signal output)

Please have a loot at the image below. I am not sure if I have missed something out.

See page 1-4 of the HSTP manual:
http://literature.rockwellautomation.com/idc/groups/literature/documents/um/1746-um121_-en-p.pdf

you need to configure it for EITHER

pulse train with direction command -OR- a CW pulse train and CCW pulse train​

I'm unsure how you have it configured.

Okay, that is great, I have been through the manual so many times. DO you know where / how it can be configured??? At this moment, everything is default, I assume.

THANK YOU A LOT!!!!!!!!

Hello,

Okay, I have been through the OEM750 Manual. I have found this information.

STEP INPUT
For every step pulse it receives on its step input, the drive will
commutate the motor to increment rotor position. To send a
step pulse to the drive, apply a positive voltage to STEP+ with
respect to STEP–. The drive registers the pulse on the rising
edge.

The step input is optically isolated. Driving the step input
1differentially will provide the best noise immunity. Your input
driver must provide a minimum of 6.5 mA—approximately 3.5
VDC. With no external current limiting resistor, the current is
controlled by the applied voltage. This is due to a fixed voltage
drop of 1.7VDC on the opto LED and the internal series
resistor (243). Increased voltage will result in increased
current.

Step Pulse Requirements
Operate the step pulse input within the following guidelines:
• 200 nanosecond pulse – minimum
• 40% – 60% duty cycle (2 MHz maximum pulse rate)

DIRECTION INPUT SIGNAL SPECIFICATION
While a positive voltage is applied to DIR+ with respect to
DIR–, the drive will commutate the motor in the clockwise
(positive) direction as it receives step pulses on its step input.
While zero voltage (or a negative voltage) is applied to DIR+
with respect to DIR–, the drive will commutate the motor in
the counterclockwise (negative) direction as it receives step
pulses.
The input is optically isolated. It may be differentially driven.
CAUTION
Reverse voltage in excess of 6VDC may damage this device.
Your input driver must provide a minimum of 8mA at 3.5VDC
to ensure proper operation. With no external current limiting
resistor, the current is controlled by the applied voltage. This
is due to a fixed voltage drop of 1.5VDC on the opto LED and
the internal series resistor (243).

Chapter 6 of the HSTP manual:
http://literature.rockwellautomation.com/idc/groups/literature/documents/um/1746-um121_-en-p.pdf
provides Application Examples that you should review and see if you can work through the information.
The driver appears to require step and direction, so you should concentrate on that.

Apparently the stepper driver is not protected against reverse voltage, so you must use from -3.5 to -6 volts only.

Hello,

Okay, 7 - 24v must be supplied to the AB 1746-HSTP1.

So, am I missing something here.

I have supplied 24 to the 1746-HSTP1. Everything work in a CW direct however I cannot get the CCW working yet.

Thanks
