I have a question regarding IONI HC in IONICUBE regarding connecting a Hengstler SinCos encoder.
My hardware configuration:
- IONI HC in IONICUBE
- 34HS59-5004D stepper motor (https://www.omc-stepperonline.com/hybrid-stepper-motor/keyway-dual-shaft-nema-34-stepper-motor-13nm-1841ozin-5a-86x86x150mm-34hs59-5004d.html?mfp=184-frame-size-mm[86%20x%2086]) with 0 548 031 Hengstler SinCos encoder ((https://www.hengstler.de/en/s_c10030301/Rotary_encoders/Sin/Cos_rotary_encoders/S21/)
I’m still making electrical connections, so I haven’t got Granity connected yet and don’t have firmware revs, etc.
Problems arise when:
I try to look up how to connect the index channel for the encoder.
How it behaves:
The Wiki (https://granitedevices.com/wiki/IONI_%26_IONICUBE_user_guide/Wiring_overview#X6_and_X8_pinout) shows both pins 14 and 15 as Z+ in SinCos mode. Is this a documentation error?
Furthermore, I can’t find any documentation of the expected electrical specification of the signal(s) in this mode.
How I would expect it to behave:
I’d expect one to be Z+ and the other to be Z- (as they are in other modes).
The A and B channels of the encoder are 1Vp-p centred on 2.5V (2048cycles/rev).
The Z channel of the encoder is also 1Vp-p centred on 2.5V, with a single peak per rev.
I need to know: Will the drive accept these signals?
My theory is that the A & B channels will be OK for direct connection. Is that correct?
I’m most concerned about the operation of the Z channel. What is the electrical spec for the Z channel?
Many thanks for your excellent products,
