No.

The issue is the GS2 supplies its own voltage for their inputs (10-volts), and your using the NPN output module, I don't think there is enough current in the 10V of the drive to operate the output module. To do your solution as you describe, you would need to purchase a relay output module C0-08TA for each drive. Your other solution is to get a CLICK CPU with the third comm port, and control each drive via Modbus, and avoid needing outputs devoted to the drives. I did that with GS1 drives with great success. I followed this document:

Well darn! I was sure hoping that would work. Unfortunately com3 is spoken for (loads programing into a stepper controller’s memory I have and am using via ASCII), com2 goes to a touch screen. Frankly I’m not sure I could handle the Modbus anyway…ok that’s probably incorrect; I did figure out this other stuff.

No doubt proper communications setups are the way to handle these sorts of problems…

Thanks for the response.

Better late than never? or maybe not

Ok, this thread is over 6 months old, but I found it while searching for something, and someone else may do the same.

Page B-7 of the GS2 manual (1st ed. rev C, 12/2006) specifically indicates the OP's suggested connection to a D0-16TD1 as being "typical ".

DCM to module common, external 24VDC across module V1 and common.

The output voltage range for the C0-16TD1 is 4-30VDC

Well, I'm sorry I said anything.

The GS2 specs for the digital input:

Input Voltage: Internally Supplied (see WARNING below)

Input Voltage Range: 4-12V

Minimum ON Current: 22 mA max

Maximum OFF Current: 1.1 mA

Partial Specs for the C0-04TRS:

Minimum Load Current 100 mA @ 5 VDC

If one does want to use a relay output, that's fine with me, but it should probably have gold plated low current contacts. A C0-08TR should be fine:

Minimum Load Current 5 mA @ 5 VDC

There is no need for the independent commons of the -04 in the OP's example.

The only reason I resurrected this thread was to point out that the configuration the OP asked about is shown in the GS2 manual as a "typical " connection.

I use two output modules to control multiple GS2s. The first is a relay module that acts just like push-buttons which connects the GS2 IO common (DCM) to the relay common and the individual relay outputs to the GS2 inputs (DIx). The next module I used is an analog voltage output module connect to the GS2 analog voltage common (ACM) and analog voltage input signal (AI) to control the speed. Directly wired with no problems. I used shielded wire which the shielding is grounded at one end only were the I/O modules are. Do not connect the shielding to the the drives. With multiple drives its OK for the DCM of each drive to share each others DCM and the same for the ACM.

If somebody could help me with this it would be swell. I need to operate the digital inputs on two GS2 drives with a Click. I’ve done this before with a bunch of electromechanical relays but this makes a very ugly setup. Looking at the IO options for the Click it seems it seems to me that the CO-16TD1 output module might do the trick without any intermediary clunky relays.

Can this work? With -24VDC to C1 of the module and +24VDC to V1 of the module I wire DCM of the GS2 drive to C1 and DI1 through DI6 to the points 1 through 6 on the module. Then do the same map for C2 and V2 and points 9 through 13 for the second GS2.

One thing I wonder about…(beyond if it will work at all that is) is DCM of the GS2 drive negative or have I got that part backwards?

Thanks to you all. Your help has allowed me, a self-taught person, to build some really cool stuff!
