Johnson Controls VFD67 Series Getting Started Manual page 33

Before the SmartStick is written to using Prog, the SmartStick will need to be inserted
NOTE
into the drive at power up or a reset command performed when the drive has been
powered up, otherwise will trip on C.dAt when Prog command executed.
For best motor performance, an autotune should be carried out after parameter copying
NOTE
has taken place.
When copying between drives of different ratings, bit parameters will not be copied.
NOTE
No Function
29 Load defaults
no: defaults are not loaded
Eur: 50Hz default parameters are loaded
USA: 60Hz default parameters are loaded
Default parameters are set by pressing the
mode after Pr 29 has been set to Eur or USA.
When default parameters have been set, the display will return to Pr 01 and Pr 10 will be
reset to L1.
The drive must be in a disabled, stopped or tripped condition to allow default parameters
NOTE
to be set. If default parameters are set while the drive is running, the display will flash
FAIL once before changing back to no.
Disconnect the electro-mechanical brake circuit before a default is performed.
WARNING
No Function
30 Ramp mode select
0: Fast ramp selected
1: Standard ramp with normal motor voltage selected
2: Standard ramp with high motor voltage selected
3: Fast ramp with high motor voltage selected
Fast ramp is linear deceleration at programmed rate, normally used when a braking
resistor is installed.
Standard ramp is controlled deceleration to prevent DC bus over-voltage trips, normally
used when there is no braking resistor installed.
If a high motor voltage mode is selected, deceleration rates can be faster for a given
inertia but motor temperatures will be higher.
No Function
31 Stop mode select
0: Coast to stop selected
1: Ramp to stop selected
2: Ramp to stop with 1 second DC injection braking
3: DC injection braking with detection of zero speed
4: Timed DC injection braking
