7I33TA Just plug it in?

retrofitting a mazak vtc-20b and it is going great, i have step and dir to all the servo drives. that is running off a 7i52s in first connecter P4, i have a 7i44 on p2, i would like to run a 7i33ta in the middle for the analog spindle. can i just plug it in or do i need a new firmware for the 5i24-24?
also seem like a lot to use a whole 7i33ta just for the spindle, maybe i could use pwm and dir with the gs2015 spindle drive?

If you spindle drive can use 5V PWM/DIR control
(and you are not using all 6 step/dir outputs on the 7I52S)
it might be easiest to use firmware that changes one of the 6
step/dir outputs on the 7I52S to PWM/DIR

the manual says it has 1 channel pulse input (33 kHz), 1 channel pulse output (33 kHz), not sure what this is maybe like stepper pulse in. im using 4 channels of the 7i52s for XYZA axis, the A is available for the spindle. still having trouble turning all the step gens on. i got it working before and i followed the forum posts that worked before but i think im doing something wrong. the machine has a spindle encoder, but the manual unclear on how to implement the pulse input. think it would be 1 cw pin, 1 ccw pin, pulse pin (step?) and some kind of enable(run) pin. have a 7i82d that i could put the pins on and use encoder and step(pulse) or pwm out on the 7i52s
