Encoder output from Sinamics V90 TTL (5V DC) and HSC S7-1200 HTL 24V DC have different voltages

I have a positioning system based on S7-1200 and Sinamics V90 + 1FL6061-1AC61-0AB1,

two axes, control - Pulse / Direction Interface.

similarly as in the example

SINAMICS V: Controlled Positioning of a V90 with S7‑1200 via the Pulse/Direction Interface, with HMI (Set 7)

https://support.industry.siemens.com/cs/document/77467940/sinamics-v%3A-controlled-positioning-of-a-v90-with-s7%E2%80%911200-via-the-pulse-direction-interface-with-hmi-(set-7)?dti=0&lc=en-WW

for control Pulse / Direction Interface I use 2 fast digital output (for each axis),

SB 1222 DC 200 kHz 6ES7222-1BD30-0XB0.

the example does not use position feedback, but I would like to use signals from the motor encoder,

Sinamics V90 has an encoder output (TTL 5V), 6 outputs (A+,A-; B+,B-; Z+,Z-),

And I would like to read it,

S7-1200 have High-Speed Counters (HSC) x6 pcs., to each HSC can connect 3 digital inputs (eg., A+, B+, Z+), for two axes I need 2xHSC (6 digital inputs),

the problem is that encoder output from Sinamics V90 TTL (5V DC),

and HSC S7-1200 HTL 24V DC, we have different voltages,

of course I could use an additional card 5V DC (eg. SB 1223 DC/DC 200 kHz 6ES7223-3AD30-0XB0),

but I'm already using SB for fast digital output SB 1222 DC 200 kHz.

What can you advise me?

What kind of equipment (converter TTL/HTL) required?

Split from Sinamics V90+S71-200=cheap Sinumerik?.

Closed cause question posted twice.

The second thread with the subject SINAMICS V90 - Encoder output (TTL) S7-1200 HSC (HTL) is published within the conference SINAMICS.
