If ControlWordEnable (06.043) = 0 then ControlWord (06.042) has no effect. If ControlWordEnable (06.043) = 1 the bits in ControlWord (06.042) are used instead of their corresponding
parameters or to initiate drive functions as shown in the table below:
Bit Corresponding paramter or function
0 DriveEnable (06.015)
1 RunForward (06.030)
2 JogForward (06.031)
3 RunReverse (06.032)
4 Forward/Reverse (06.033)
5 Run (06.034)
6 NotStop (06.039)
7 Auto / manual
8 Analog / Preset reference
9 JogReverse (06.037)
10 Not used
11 Not used
12 Trip drive
13 Reset drive
14 Watchdog
Because of the limited number of segments on drives with an LED display, these drives will indicate the parameter value as a decimal value rather than a binary value.
Bits 0-7 and bit 9: Sequencer control
When Auto/manual bit (bit7) = 1 then bits 0 to 6 and bit 9 of the ControlWord (06.042) become active. The equivalent parameters are not modified by these bits, but become inactive when the
equivalent bits in the ControlWord (06.042) are active. When the bits are active they replace the functions of the equivalent parameters.
Bit 8: Analogue/preset reference
The state of Analogue/Preset Reference (bit 8) is written continuously to ReferenceSelectFlag2 (01.042). With default drive settings (i.e. ReferenceSelector (01.014) = 0) this selects
AnalogReference1 (01.036) when bit 8 = 0 or PresetReference1 (01.021) when bit8 = 1. If any other drive parameters are routed to ReferenceSelectFlag2 (01.042) the value of this
parameter is undefined.
Bit 10 and bit 11: Not used
The values of these bits have no effect on the drive.
Bit 12: Trip drive
If bit 12 = 1 then a ControlWord trip is repeatedly initiated. The trip cannot be cleared until bit 12 = 0.
Bit 13: Reset drive
If bit 13 is changed from 0 to 1 a drive reset is initiated. Bit 13 does not modify DriveReset (10.033).
Bit 14: Watchdog
A watchdog system can be enabled or serviced each time bit 14 is changed from 0 to 1. Once bit 14 has been changed from 0 to 1 to enable the watchdog, this must be repeated every 1s or
else a Watchdog trip will be initiated. The watchdog is disabled when the trip occurs and must be re-enabled if required when the trip is reset.

Note: Size 1 drives only have a single fan speed and so some of the operational modes are not available.
If CoolingFancontrol (06.045) = 0 the cooling fan in the drive is off.
Some option modules consume more power than others and so if one of the higher power consumption modules is fitted to the drive, the drive will trip OHtControl if StackTemperature
(07.004) is above an internally set threshold (drive power rating dependant), and the option module will be forced to go into standby.
If CoolingFancontrol (06.045) = 1 the cooling fan in the drive is forced to run at full speed.
If CoolingFancontrol (06.045) = 2 the cooling fan in the drive is controlled by the values of StackTemperature (07.004) and CurrentMagnitude (04.001) . The fan will run at full speed for at
least 20 seconds if StackTemperature (07.004) is greater than a frame dependent threshold (60 °C for size 1 & 2 or 50 °C for size 3 & 4) or CurrentMagnitude (04.001) is greater than 75%
of Drivecurrentrating (11.068), otherwise the cooling fan is off. If neither of the above conditions are causing the fan to run, the fan will run at low speed if one of the higher power consumption
option modules is fitted and StackTemperature (07.004) is above the internally set threshold. The fan will not turn off until StackTemperature (07.004) falls to 5°C below the internally set
threshold.
If CoolingFancontrol (06.045) = 3 is the same as CoolingFancontrol (06.045) = 2 but the cooling fan never turns off but runs at low speed when full speed is not being called for. This mode is
not available on size 1 and so if selected, mode 2 is used instead.
If CoolingFancontrol (06.045) = 4 the cooling fan in the drive is at low speed continuously. This mode is not available on size 1 and so if selected, mode 1 is used instead.
