Analog Outputs - Baldor NextMove ES Installation Manual

4.3.2 Analog outputs

The four analog outputs are available on a range of pins, as shown in section 4.2.1.
Four independent analog outputs (model dependent).
H
Output range: ±10 VDC (±0.1%).
H
Resolution: 12-bit.
H
Output current: 10 mA maximum.
H
Update frequency: 10 kHz maximum (adjustable using the LOOPTIME keyword, factory
H
default 1 kHz).
Mint and the Mint Motion Library use analog outputs Demand0 and Demand1 to control drive
amplifiers. Demand outputs 0 and 1 are used by axes configured as servo (see section 6.4.1).
The Demand2 and Demand3 outputs may be used as general purpose analog outputs. See
the DAC keyword in the Mint help file.
The analog outputs may be used to drive loads of 1 kΩ or greater. Shielded twisted pair cable
should be used. The shield connection should be made at one end only.
