Phase Pwm; Cooling Fan Control - Santerno sinus M User Manual

10.21 2 Phase PWM

Group Display
Function Group H48
2
Heat loss and leakage current from inverter can be reduced when H48 is set to 1(2 phase PWM)

according to the load ratio.

10.22 Cooling fan control

Group Display
Function
H77
group 2
Control the On/ Off of the heatsink cooling fan.

When it is set to 0:

-. Cooling fan begins to operate when power is ON.
-. Cooling fan is stopped when inverter main circuit voltage becomes low due to power off.
When it is set to 1:

-. Cooling fan begins to operate when power is turned ON with RUN command ON.
-. Cooling fan is stopped when RUN command is Off and when the deceleration ramp is end.
-. Cooling fan keeps operating when heatsink temperature exceeds a certain limit regardless
of RUN command.
-. Used when frequent Run/Stop or long time stop is required. This may make the cooling fan
life longer.
