powered down, reset on the keypad or by re-
enabling the drive.

0 : Minimum speed
1 : Previous speed
2 : Minimum speed (Auto-run)
3 : Previous speed (Auto-run)
1
If set to 0 or 2, drive will always start from
minimum speed.
If set to 1 or 3, drive ramps up to the operating
speed prior to the last STOP command.
If set to 2 or 3, the status of digital input 1
controls drive to start or stop. The start and
stop button on the drive will not function in this
case.
P-32
DC injection on
stop
0 to 25.0s
0
(disabled)
When > 0, DC injection braking activated when
speed reaches zero with stop signal applied.
Only applied on disable (Stop), not on enable.
Uses the level set in P-11.
P-33

0 : Disabled
1 : Enabled

When enabled, drive starts from detected
motor rotor speed. Short start delay possible if
rotor stationary. Recommended for high inertia
load applications.
For Size 1 drives, P-33 = 1 enables DC
injection braking on enable. The duration and
levels are set by P-32 and P-11 respectively.
P-34

0 : Disabled
1 : Enabled with s/w protection
2 : Enabled without s/w
protection
0
Software protection for Invertek standard brake
resistors (200W).
For Non-Invertek approved resistors and higher
braking applications set to 2.

When set to OP-buS, MODBUS disabled.
Communication with PDA, PC and Optiport E2
possible
Setting a baudrate enables MODBUS at that
baudrate and disables OP-buS.
The time before a trip in the event of a
communication loss can be set in milliseconds.
Setting “0” disables the communications trip.
t 3000
(3 second
trip)
r 30, 100, 1000, 3000 (ms))
“t” indicates the drive will trip if time exceeded.
“r” indicates the drive will ramp to stop if time
exceeded.

power down
1: Read-only. No changes
allowed.
0
Controls user access to parameters. When P-
38 = 0, all parameters can be changed and will
be stored automatically. When P-38 = 1,
parameters are locked and cannot be changed.
Introduces an offset to the analog input level
with a resolution 0.1%. e.g. 10% = 1V = 0Hz
P-39 Analog input offset -500.0 … 500.0% 0%
Custom scaling factor applied to drive speed. If
P-10 = 0, speed in Hz scaled by this factor. If
P-10 > 0, speed in RPM scaled. Displayed as
real-time variable on the drive display,
indicated by a “c”.

P-41
User PI
Proportional Gain
0.0 ... 30.0 1.0
Higher value used for high inertia. Too high a
value gives instability.
P-42
User PI Integral
time constant
0.0s ... 30.0s 1.0s
Higher value gives slower, more damped
response.
If an increasing feedback signal should
increase the speed of the motor, set to
‘Inverse’ mode.

0
Sets the source for the PI control reference
signal. When set to 1, analog input 1 is used.
P-45
User PI digital

0 … 100% 0.0 % Sets the preset reference used when P-44 = 0.
P-46
User PI feedback

0 : 2nd analog input (T4)
1 : 1st analog input (T6)
2 : motor load current

“t” indicates the drive will trip if signal removed
when drive is enabled.
“r” indicates the drive will ramp to Preset Speed
1 if signal is removed when the drive is enabled
