bit 12 is set to one a CL.bt trip is initiated. The trip cannot be cleared until the bit is set to zero.
Bit 13: Reset drive
When the control word is enabled (Pr 6.43) bit 13 of the control word becomes active. (Bit 7 of the control word has no effect on this function.) When
bit 13 is changed from 0 to 1 the drive is reset. This bit does not modify the equivalent parameter (Pr 10.33).
Bit 14: Keypad watchdog
When the control word is enabled (Pr 6.43) bit 14 of the control word becomes active. (Bit 7 of the control word has no effect on this function.) A
watchdog is provided for an external keypad or other device where a break in the communication link must be detected. The watchdog system can be
enabled and/or serviced if bit 14 of the control word is changed from zero to one with the control word enabled. Once the watchdog is enabled it must
be serviced at least once every second or an “SCL” trip occurs. The watchdog is disabled when an “SCL” trip occurs, and so it must be re-enabled
when the trip is reset.
0: Fan speed controlled by drive
1: Fan runs at full speed
When this parameter is set to 0, the fan is controlled by the drive. If the heatsink temperature is above 60
o
C or the drive output current (Pr 4.01) is
above 75% of the drive rated current, the fan will switch on and run at full speed for a minimum of 10s. After 10s, if the heatsink temperature falls
below 60
o
C or the drive output current falls below 75% of the drive rated current, the fan will switch off. If the temperature remains above 60
o
C or the
drive output current remains above 75% of the drive rated current, the fan will continue running at full speed.
When this parameter is set to 1, the fan runs at full speed at all times when the drive is powered up.
