Parameters and Programming 5-5
Program Group Parameters
This group contains parameters whose values can be programmed. Refer to
Programming Example earlier in this chapter. Unless otherwise stated, parameters
that are programmed while the drive is running take immediate effect.

No. Parameter Name/Description Min./Max. Range Units
17 [Fault Buffer 0]
This parameter stores the last fault that occurred. If the same fault occurs multiple times in
a row, it will be stored once. After a “reset defaults” (P56) this will set this parameter to
F48 - Reprogram Fault. As faults occur, the previous value of this parameter is moved to
P18 - [Fault Buffer 1].
0/48 Numeric Value
18 [Fault Buffer 1]
This parameter stores the second most recent fault that occurred. After a “reset defaults”
(P56) this will set this parameter to 0 (No active fault). As faults occur, the value of this
parameter will be overwritten by P17 - [Fault Buffer 0]. The previous value of this parameter
is moved to P19 - [Fault Buffer 2].
0/48 Numeric Value
19 [Fault Buffer 2]
This parameter stores the third most recent fault that occurred. After a “reset defaults” (P56)
this will set this parameter to 0 (No active fault). As faults occur, the value of this parameter
will be overwritten by P18 - [Fault Buffer 1].

30 [Accel Time 1]
Time for the drive to ramp from 0.0 Hz. to P33 - [Maximum Frequency]. The rate
is linear for any increase in command frequency unless P53 - [S-Curve] is set to
a value other than “0”. Setting this to 0.0 sec. gives 0.1 sec acceleration with the
initial current limit turned off. This allows quicker acceleration times for low inertia
systems. For medium to high inertia systems, the minimum value should be 0.1
sec.
