I am using the GS20 VVFD for a Centroid Hickory conversion on my 5hp bed mill. The parameters that have been changed are per the Centroid Tech Bulliten as follows,

Parameter Description Value

P00.02 Restore to default 10 = set parameters to 60 Hz defaults

P00.04 Drive display 7

P00.20 Frequency command source 2 = external analog input

P00.21 Operation command source 1 = external terminals

P00.22 Stop method 0 = decel ramp

P00.31 Control method 1 = external control terminals

P01.00 Maximum operation frequency 120

P01.01 Motor base frequency 60 Hz

P01.02 Motor rated voltage 230

P01.10 Output frequency upper limit 599.0

P01.12 Acceleration time 3.0

P01.13 Deceleration time 3.0

P02.04 Terminal DI4 function 5 = fault reset

P02.16 Terminal DO1 function 6 = zero speed

P3.00 Source of frequency command 1 = frequency determined by 0-10VDC on AI1

P03.20 Analog Output 3 = output current (CNC11 & CNC12 only)

P05.01 Motor full-load current 13.6

P05.03 Motor rated speed 1755

P06.01 Overvoltage Stall Prevention 0 (disable) if braking resistor is installed.

P06.44 STO Latch Selection 1 (no latch) if STO circuit is used

All other parameters are Factory.

Brake resistor is hooked to B1 and B2 with the factory jumper plate between DC+/1 and +2/B1
