I have a Frenic 5000G9 VFD and want to hook it up to a gecko g540. Can the G540 run this VFD or does the G540 output the wrong type of signal to control it? I have attached the paper work for the drive if someone doesn't mind going through it for me. It's all greek to me. I know the Gecko outputs a analog signal but if I read page 33 right the Frenic will accept analog or digital.
9) ANALOG OUTPUT: This is a 0V to +10V opto-isolated analog output intended for use with VFD drives. VFD OUT goes to 0VDC while the G540 is disabled. Connect VFD GND, VFD OUT and VFD +10V to the VFD drive inputs. Make sure the VFD drive positive voltage does not exceed +12VDC. Do not short VFD OUT to any other terminal. Do not reverse polarity to VFD GND and VFD +10V or the G540 may be damaged.

look at page 33 of the pdf
looks like it will , wire it analog voltage like on pg 33
