Heden motors with Preston mdr1/hu1

[richard bellon]

Hi all

 

Can u use heden motors with prwston hu1/mdr1?

[Jens Piotrowski SOC]

The digital ones, yes. 26ve or 21ve

[richard bellon]

Ok, tx

I woulda thought that my m28-vp and m26p would've worked

No, the "P" series motors are analog and use a potentiometer to read out position data. The "E" series uses an encoder, and is digital. All Preston systems (save for the Micro Servo, a long long discontinued product) use digital motors.

The basic rule is, if it has a Lemo 1B 7 pin on the motor, it will probably work. This rule must be ignored in the case of the Tilta motors, as they have copied the industry standard connector, but have their own pinouts and control systems so the motors won't work with normal digital controls, although they do look like they should.

I have that setup. Works beautifully!

It's also not true in the case of the Heden M26PT or M28VPT combo analog zoom/focus motors which use the same Lemo 1B 7 pin connector but have both analog potentiometer and tachometer so they can be used as zoom or focus motor.
