18. Speed Command Input shall be accomplished using any of the following:
a. Keypad
b. Two (2) Analog inputs, each capable of accepting a 0 to 20mA, 4 to 20mA, 0 to 10V, 2 to 10V
signal, and direct NI 1000 temperature sensor input.
c. Serial Communications
I. Communications
1. The VFD shall have an RS-485 and Ethernet as standard. The standard embedded protocols shall be
BACnet MS/TP, BACnet IP, Modbus RTU, Modbus TCP, Siemens APOGEE P1 (FLN) protocol and
Johnson Controls. Inc. N2 Metasys protocol. There shall be an optional LON (LONMARK) interface.
2. Serial communication capabilities shall include, but not be limited to, run-stop control; speed set
adjustment, proportional/integral/derivative PID control (Setpoint) adjustments and accel/decel time
adjustments. The drive shall have the capability of allowing the DDC to monitor feedback such as
process variable feedback, output speed/frequency, current (in amps), percent torque, power (kW),
relay outputs, digital inputs and diagnostic warning and fault information. Additionally, remote (LAN)
VFD fault reset shall be possible. A minimum of 15 field parameters shall be capable of being
monitored.
J. Drive Optional Features
1. Optional features shall be furnished and mounted by the drive manufacturer. All optional features shall be
UL Listed by the drive manufacturer as a complete assembly and carry a UL508 label.
2. The VFD shall have an optional integrated disconnect switch which has the same footprint as a
drive without an integral disconnect switch.
3. The VFD shall be capable of adding additional I/O as required for the system. The additional I/O
shall mount in the drive and not require bypass configuration. Up to three (3) optional I/O
boards can be included in each drive:
a. Six (6) additional programmable digital inputs or outputs.
b. Five (5) digital inputs with a relay output.
c. Two (2) relay outputs with a thermistor.
d. One (1) Analog Input and two (2) analog outputs.
e. Three (3) relay outputs.
f. One (1) analog output, and one (1) digital output.
g. Ni100 Sensor Card.
