The GS4 has one high-speed pulse train output: FO. This pulse train output is based on the actual
main frequency output of the drive. A scaling factor is available to adjust the frequency.
P3.38 Frequency Output Scaling Factor:
• Actual FO pulses per second output = GS4 output frequency (Hz) x P338
Drive FO output is limited to 30V@ 30mA max. Max frequency is 100kHz (50% duty cycle).
The PLC high-speed input will have a certain amount of resistance built-in (P2-HSI module has 2kΩ
resistance). The drive terminal FO needs to see a minimum of 1kΩ resistance.
