When the Drive parameters are stored to the Quickey, if the current mode is rEAD or
Prog, it is stored in the Quickey as no. If the current mode is Auto or boot, these are
stored as Auto or boot.
The Quickey memory contains Drive size specific information. If the contents
of the Quickey are copied to a Drive of a different rating to that previously
programmed, the Drive will trip with the code C.rtg. This signifies that all of
the parameters apart from the Drive rating specific parameters have been
copied from the Quickey.
The Quickey should only be installed or removed when power to the Drive has
been switched off.
no - defaults are not loaded
Eur - 50Hz default parameters are loaded
USA - 60Hz default parameters are loaded
After disabling the Drive, set parameter 29 to the desired value, press the Mode key
once and then the Stop/Reset key for 1 second. When default parameters have been
set, the display will return to parameter 01 and parameter 10 will be reset to L1.
0 - Fast ramp selected
The deceleration ramp will fall at the programmed deceleration rate (subject to current
limits programmed). If the deceleration ramp is too fast for the load inertia, the Drive
could trip on overvoltage (OU).
Fast ramp is normally the mode selected when using a braking resistor.
1 - Standard ramp with normal motor voltage
The Drive controls the motor voltage according to the motor rated voltage entered in
parameter 08. The Drive may extend the deceleration ramp to prevent the Drive
tripping on overvoltage (OU) if the load inertia is too high for the programmed
deceleration ramp.
2 - Standard ramp with high motor voltage
The Drive allows the motor voltage to increase by a factor of 1.2 times the motor rated
voltage entered in parameter 08. This increase in voltage saturates the motor, which
increases the losses and therefore reduces the amount of regenerated energy
transferring from the motor to the DC Bus for a given deceleration rate. The Drive may
extend the deceleration ramp to prevent the Drive tripping on overvoltage (OU) if the
load inertia is too high for the programmed deceleration ramp.
For a given amount of energy, mode 2 allows faster deceleration than mode 1,
providing that the motor can withstand the extra losses.
boot
When this is set, it provides exactly the same functionality as Auto but in
addition it will overwrite the Drives EEPROM memory parameter settings
with the Quickey parameter settings when the Drive is powered up. These
parameters are then automatically saved by the Drive. This mode provides
a very fast and efficient way of re-programming a number of Drives.
