Appendix A—Description of parameters
Code Modbus ID Parameter
P6.1.13 319 Underload F0 Torque
This parameter gives value for the minimum torque allowed at zero frequency.
If you change the value of Para ID486, nominal motor current, this parameter is automatically restored to the
default value.
P6.1.14 320 Underload Time Limit
This is the maximum time allowed in an underload condition. An internal up/down counter counts the
accumulated underload time. If the underload counter value goes above this limit, the protection will cause a
trip according to Para ID317. If the drive is stopped, the underload counter is reset to zero.

P6.1.15 333 Thermistor Fault Response
This parameter is used to define the device reaction after a "Thermistor Fault Motor" condition occurs. This
failure could be device dependent.
0 = No response
1 = Warning
2 = Fault, stop mode after fault according to standard stop mode.
3 = Fault, stop mode after fault always by coasting
P6.1.16 337 PT100 Fault Response
This parameter sets the device reaction after a "PT100 Fault" condition has occurred. This condition could be
possible device dependent.
0 = No response
1 = Warning
2 = Fault, stop mode after fault according to standard stop mode
3 = Fault, stop mode after fault always by coasting
P6.1.17 2159 Preheat Mode
This parameter defines the location for enabling or disabling the preheat function where this is used in
the case depending on where the temperature is being read from the drive will turn on the output to allow
current to flow to the motor if the temperature of the drive or PT100 sensor drops, this is typically used when
the motor is not running.
0 = Disable
1 = Enable
