-
Enables access to Extended and Advanced Parameter Groups. This parameter must be set to the value programmed in P-37 (default:
101) to view and adjust Extended Parameters and value of P-37 + 100 to view and adjust Advanced Parameters. The code may be
changed by the user in P-37 if desired.

Analog Input 1 Signal Format
See Below
U0-10
-
= Uni-polar 0 to 10 Volt Signal. The drive will remain at minimum speed (P-02) if the analog reference after scaling and
offset are applied is =<0.0%. 100% signal means the output frequency / speed will be the value set in P-01.
= Uni-polar 0 to 10 Volt Signal, bi-directional operation. The drive will operate the motor in the reverse direction of rotation
if the analog reference after scaling and offset are applied is <0.0%. E.g. for bidirectional control from a 0
–
10 volt signal, set P-35 =
200.0%, P-39 = 50.0%
= 0 to 20mA Signal
= 4 to 20mA Signal, the TECDrive will trip and show the fault code
if the signal level falls below 3mA
= 4 to 20mA Signal, the TECDrive will run at Preset Speed 1 (P-20) if the signal level falls below 3mA
= 20 to 4mA Signal, the TECDrive will trip and show the fault code
if the signal level falls below 3mA
= 20 to 4mA Signal, the TECDrive will run at Preset Speed 1 (P-20) if the signal level falls below 3mA
= 10 to 0 Volt Signal (Uni-polar). The drive will operate at Maximum Frequency / Speed if the analog reference after scaling
and offset are applied is =<0.0%
P-17
Maximum Effective Switching Frequency
4
32
8
kHz
Sets maximum
effective switching frequency of the drive. If “rEd” is displayed
when the parameter is viewed, the switching frequency has
been reduced to the level in P00-32 due to excessive drive heatsink temperature.

-
Selects the function assigned to the relay output. The relay has two output terminals, Logic 1 indicates the relay is active, and
therefore terminals 10 and 11 will be connected.
0
:
Drive Enabled (Running)
. Logic 1 when the motor is enabled
1: Drive Healthy
. Logic 1 when power is applied to the drive and no fault exists
2
:
At Target Frequency (Speed)
. Logic 1 when the output frequency matches the setpoint frequency
3: Drive Tripped
. Logic 1 when the drive is in a fault condition
4
:
Output Frequency >= Limit
. Logic 1 when the output frequency exceeds the adjustable limit set in P-19
5
:
Output Current >= Limit
. Logic 1 when the motor current exceeds the adjustable limit set in P-19
6
:
Output Frequency < Limit
. Logic 1 when the output frequency is below the adjustable limit set in P-19
7
:
Output Current < Limit
. Logic 1 when the motor current is below the adjustable limit set in P-19
8: Analog Input 2 > Limit
. Logic 1 when the signal applied to analog input 2 exceeds the adjustable limit set in P-19
9: Drive Ready to Run
. Logic 1 when the drive is ready to run, no trip present.

Changing the value of P-09 will reset all values to factory default settings
P-24
2nd Ramp Time (Fast Stop)
0.00
600.0
0.00
s
This parameter allows a 2
nd
ramp time to be programmed into the drive.
This ramp time is automatically selected in the case of a mains power loss if P-05 = 2 or 3. When set to 0.00, the drive will coast to
stop.
When using a setting of P-
15 that provides a “Fast Stop”
function, this ramp time is also used.
In addition, if P-24 > 0, P-02 > 0, P-26=0 and P-27 = P-02, this ramp time is applied to both acceleration and deceleration when
operating below minimum speed, allowing selection of an alternative ramp when operating outside of the normal speed range,
which may be useful in pump and compressor applications.
