0-77 DST/Summertime End
Range: Function:
0 N/A* [0 - 0 N/A] Sets the date and time when summertime/DST ends. The date is programmed in the format selected
in par.0-71
Date Format
.
1-00 Configuration Mode
Option: Function:
[0] * Open loop Motor speed is determined by applying a speed reference or by setting desired speed when in Hand
Mode.
Open Loop is also used if the frequency converter is part of a closed loop control system based on
an external PID controller providing a speed reference signal as output.
[3] Closed loop Motor Speed will be determined by a reference from the built-in PID controller varying the motor
speed as part of a closed loop control process (e.g. constant pressure or flow). The PID controller
must be configured in par. 20-**, Drive Closed Loop or via the Function Setups accessed by pressing
the [Quick Menus] button.
This parameter can not be changed when motor is running.
NB!
When set for Closed Loop, the commands Reversing and Start Reversing will not reverse the direction of the motor.
1-90 Motor Thermal Protection
Option: Function:
The frequency converter determines the motor temperature for motor protection in two different
ways:
• Via a thermistor sensor connected to one of the analog or digital inputs (par.1-93
Ther-
mistor Source
).
• Via calculation (ETR = Electronic Thermal Relay) of the thermal load, based on the actual
load and time. The calculated thermal load is compared with the rated motor current
I
M,N
and the rated motor frequency f
M,N
. The calculations estimate the need for a lower
load at lower speed due to less cooling from the fan incorporated in the motor.
[0] * No protection If the motor is continuously overloaded and no warning or trip of frequency converter is wanted.
[1] Thermistor warning Activates a warning when the connected thermistor in the motor reacts in the event of motor over-
temperature.
[2] Thermistor trip Stops (trips) the frequency converter when the connected thermistor in the motor reacts in the
event of motor over-temperature.
[3] ETR warning 1
[4] * ETR trip 1
[5] ETR warning 2
[6] ETR trip 2
[7] ETR warning 3
[8] ETR trip 3
[9] ETR warning 4
[10] ETR trip 4
ETR (Electronic Thermal Relay) functions 1-4 will calculate the load when set-up where they were selected is active. For example ETR-3 starts calculating
when set-up 3 is selected. For the North American market: The ETR functions provide class 20 motor overload protection in accordance with NEC.
