Study notes

Control mode is SVC (sensorless vector control) or V/Hz.
Input and output are both three-phase at 460 VAC nominal.
Amperage rating is 143 A; variable torque amperage rating is 150 A.
RS-485 (RJ12) port runs Modbus RTU, Modbus ASCII and BACnet at up to 115.2k baud.
BACnet is named in the document but has no matching protocol entry in this reference list.
Optional EtherNet/IP and Modbus TCP cards are available; an EDS file and a Rockwell AOI are provided for the EtherNet/IP card.
Enclosure is open frame; IP ratings are stated as IP00 and IP20.
Output frequency range 0.1-599 Hz; carrier frequency range 2-15 kHz.
Analog I/O: 3 input channels (11-bit resolution) and 2 output channels (10-bit resolution).
Discrete I/O: 8 sinking/sourcing 24 VDC inputs and 4 relay/sinking/sourcing outputs (Form C SPDT relays).
Embedded PLC is programmed in ladder (GSLOGIC software); drive configuration uses GSOFT2.
Shipping weight is listed as 130 lb; agency compliance is UL Listed File E198015, CE and RoHS.

Safety

Safe Torque Off (STO) is built-in.
A user-supplied external fuse is required.
An external dynamic braking unit is required; the drive is not internally bypassed.
Operating temperature range is -10 to +50 °C.
The drive is open frame (IP00) construction.
Only 3-phase induction motors are listed as the intended load.
