0x16 Write Multiple Registers (for motor speeds only)

A request to use a function that is not available will return an illegal function exception.

All registers are 16 bits wide with addresses using the standard MODICON protocol. Floating point values

use the standard IEEE 32-bit format occupying two contiguous 16 bit registers. ASCII values are stored with

two characters (bytes) per register in hexadecimal format.

Motor Speed

Motors are operated simply by sending the desired speed to each motor's speed register. Positive percent-

ages result in CW (forward) rotation while negative percentages result in CCW (reverse) rotation.

FORWARD: +60 to +100% | REVERSE: -60 to -100% | STOP: 0%

Speeds below 60% may result in a stalled motor and should not be used.

Included power supply is sufficient to drive a single motor at a time.

Driving multiple motors simultaneously may cause the power supply voltage to drop below acceptable

levels and put the pump into a fault protection mode requiring a power cycle.

To drive multiple motors reliably, provide 0.5A/Motor (2.1mm jack, center positive)

Motor Life

Motor life and service intervals can be tracked by observing the pump motors' accumulated run time which

is tracked in seconds in a 32-bit unsigned integer register for each pump motor.

Timeout

Timeout value (seconds) can be set to shut off all pumps in the even no communication is receieved from

the master device within a set period of time.
