[4] Com cnt stop w/rst Same as [3] but after each precise stop the number of pulses counted during ramp down 0 rpm is
reset.
[5] Comp cnt stop w/o r Same as [3] but the number of pulses counted during ramp down to 0 rpm is deducted from the
counter value in par. 1-84
Precise Stop Counter Value .
This parameter cannot be adjusted while the motor is running.
1-84 Precise Stop Counter Value
Range: Function:
100000* [0 - 999999999 ] Enter the counter value to be used in the integrated precise stop function, par. 1-83 Precise Stop
Function
.
The maximum permissible frequency at terminal 29 or 33 is 110 kHz.
1-85 Precise Stop Speed Compensation Delay
Range: Function:
10 ms* [0 - 100 ms] Enter the delay time for sensors, PLCs, etc. for use in par. 1-83 Precise Stop Function . In speed
compensated stop mode, the delay time at different frequencies has a major influence on the stop
function.
3.3.9 1-9* Motor Temperature
Parameters for setting the temperature protection features for the motor.
1-90 Motor Thermal Protection
Option: Function:
The frequency converter determines the motor temperature for motor protection in three different
ways:
• Via a thermistor sensor connected to one of the analog or digital inputs (par. 1-93
Ther-
mistor Source
). See section PTC Thermistor Connection .
• Via a KTY sensor connected to an analog input (par. 1-96
KTY Thermistor Resource ). See
section
KTY Sensor Connection .
• Via calculation (ETR = Electronic Terminal 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 Continuously overloaded motor, when no warning or trip of the frequency converter is required.
[1] Thermistor warning Activates a warning when the connected thermistor or KTY-sensor in the motor reacts in the event
of motor over-temperature.
[2] Thermistor trip Stops (trips) frequency converter when connected thermistor or KTY sensor in the motor reacts in
the event of motor over-temperature.
The thermistor cut-out value must be > 3 k.
Integrate a thermistor (PTC sensor) in the motor for winding protection.
