Installation & Operation
Manual Control Mode:
In Manual control mode, the motor speed is set using the onboard potentiometer. Onboard potentiometer rotation is CW to increase
the motor output.
Analog Control Mode:
In ANALOG control mode, the motor output is set using an external 0-10 VDC demand signal.
Network Control Mode:
In NETWORK control mode, the motor output is set using MODBUS Register 2. Motor output is specified as a value from 0 to 100
representing a percentage of motor torque output. Each ENV1028 in a MODBUS network must be set to a unique address. The address
value is set in binary using the eight DIP switches of switch bank (S2). A maximum of 200 ENV1028 devices is
recommended per local area network(LAN). If an Titus ACC Control Console is the MODBUS master, then addresses should be
assigned within the address range supported by the Control Console. Address zero should not be used as it is reserved for global
commands. Address switch settings are only checked by the ENV1028 at power-up. Power must be cycled (OFF/ON) before
affected changes take place.
Registers relevant to this mode:
• Register 1 “Start/Stop” (R/W)
– To enable motor, write a value of 1; To disable motor, write a value of 0
• Register 2 “Motor Set Speed” (R/W)
– Motor Target speed value. Values may be written from 0 to 100
• Register 6 “RPM” (R)
– Motor RPM. Read from the motor
• Register 12 “Actual Motor Speed Instruction” (R)
– Speed control signal applied to the motor by the ENV1028.
(R/W) = Read/Write, (R) = Read Only
