Multi-function Compact Inverter 3G3MX2-EV2 User’s Manual (I666-E1)
The operation when the Cooling Fan Operation (b092) is set to 01 (Enabled only during operation) or
02 (Dependent on cooling fin temperature) is changed as follows.
Refer to 7-8-13 Cooling Fan Operation on page 7-86 for cooling fan operation.
01: Enabled only during
operation
It operates under the following conditions.
• During operation (Stops 5 minutes after
operation stop)
• For 5 minutes after power-on
It operates under the following conditions.
• During operation (Stops if fin tempera-
ture falls below 50°C for 3 minutes after
operation stop)
• Even while stopped, if fin temperature
exceeds 60°C (Stops if fin temperature
falls below 50°C for 3 minutes)
02: Dependent on
cooling fin temperature
It operates under the following conditions.
• Cooling fin temperature of approxi-
mately 45°C or higher (Stops when it
falls below 45°C)
It operates under the following conditions.
Cooling fin temperature of approximately
40°C or higher (Stops if fin temperature
falls below 40°C for 3 minutes)
Regarding the fatal fault signal (MJA) of multi-function output, the errors that can be output are changed
as follows. The fatal fault signal (MJA) turns ON when an alarm indicated with “Yes” in the table below
occurs.
The 3G3MX2-EV2 Series Inverter does not output the MJA when a Current detector error (E10), CPU
communications error (E22), or Main circuit error (E25) occurs. Refer to 7-8-19 Fatal Fault Signal (MJA)
on page 7-89 for information on the fatal fault signal (MJA) of multi-function output.
