I/O Control Parameters
94 S1A53838 09/2011
40 [Mot param. switch]
Motor control parameter
switching V/Hz, current
limit, acceleration/decel-
eration pattern
CAUTION
RISK OF DAMAGE TO THE MOTOR
z The parameter switching function disables motor thermal protection.
z The use of external overload protection is required when using motor switching.
Failure to follow these instructions can result in death, serious injury, or equip-
ment damage.
OFF: 1
st
motor control parameter set active:
([Mot cont. mode sel.] (Pt), [Motor rated freq.] (uL), [Motor rated voltage] (uLu), [Mot
Voltage Boost] (ub), [Motor thermal prot.] (tHr), [Acceleration time 1] (ACC), [Decel-
eration time 1] (dEC),
[Acc/dec 1 pattern] (F502), [Motor Current Limit] (F601))
ON: 2
nd
motor control parameter set active:
(Pt = 0, F170, F171, F172, F173, F185, F500, F501, F503)
41 [(+) speed] OFF: No motor speed increase
ON: Motor accelerates
42 [(-) speed] OFF: No motor speed reduction
ON: Motor decelerates
43 [+/- clear] OFF to ON transition clears frequency level set by +/- speed inputs
44 [+/- SPD, FLT CLR] OFF to ON transition clears frequency level set by +/- speed inputs
ON to OFF transition clears a detected fault (if cause of detected fault has been cleared)
45 [Inv Ext. fault]
Inversion of external de-
tected fault signal (see
also input function 11,
page 91
)
OFF: Motor stops according to method set by parameter [Ext. fault stop Mode] (F603)
Embedded display terminal displays E detected fault
ON: No external detected fault
46 [Ext. Th fault]
External overheating in-
put (see also input func-
tion 47)
OFF: No external overheating
ON: Motor stops, embedded display terminal displays OH2
47 [Inv Ext. Th fault]
Inversion of external over-
heating input (see also in-
put function 46)
OFF: Motor stops, embedded display terminal displays OH2
ON: No external overheating
48 [Forced local] OFF: No forced local function
ON: Control of the drive is forced to mode set by [Frequency mode sel] (FMOd), [Com-
mand mode sel] (CMOd), and [Remote spd ref 2] (F207).
49 [3-wire] OFF: Motor ramps down to a stop
ON: drive ready for operation
51 [Reset kWh]
Clear accumulated power
consumption kWh display
OFF: No function
ON: Clears kWh memory
52 [Forced mode]
DANGER
LOSS OF PERSONNEL AND EQUIPMENT PROTECTION
When
F650 is set to 1 or 2 and a logic input set to function "52" is activated, all the
drive controller protection will be disable.
• Logic input should not be enable on function 52 for typical applications...
• Logic input should be enable on function 52 only in extraordinary situations where
a thorough risk analysis demonstrates that the presence of adjustable speed drive
protection poses a greater risk than personnel injury or equipment damage.
Failure to follow these instructions will result in death or serious injury.
This function enables the "Forced fire" mode.
In this mode, all the detected fault will be ignored or if it is a hardware trip, the drive will
be reset to try to restart.
OFF: No function
ON: Motor runs at speed set by F294
Note: F650, F659 and F294 must be configured to activate this function.
