Meaning
I2T model warning threshold
Unit: %
I2T model error threshold
Unit: %
Overtemperature warning threshold
Unit: 0.1 °C
This value is affected by automatic scanning.
(see Automatic scanning of the electronic type plates
[} 143])
Overtemperature error threshold
Unit: 0.1 °C
This value is affected by automatic scanning.
(see Automatic scanning of the electronic type plates
[} 143])
Thermal time constant
Unit: 0.1 s
This value is affected by automatic scanning.
(see Automatic scanning of the electronic type plates

Meaning
Maximum subindex
Manual release of the motor holding brake
Time the holding brake requires for opening (releasing)
after the current was applied
This value is affected by automatic scanning.
(see Automatic scanning of the electronic type plates
[} 143])
Time the holding brake requires for closing (holding)
after the current was switched off
This value is affected by automatic scanning.
(see Automatic scanning of the electronic type plates
[} 143])
Time the amplifier waits, until the rotation speed
reaches the stand still window after stop request (set
rotation speed 0 or Torque off). If the set waiting time
is exceeded, the holding brake is triggered indepen-
dently of the rotation speed.
Note:
For rotatory axes and the setting „torque off" in error
case, this parameter has to be set at least to the „coast
to the stop" time of the axis.
For suspended (hanging) axes and the setting „torque
off" in error case, this parameter has to be set to an
appropriate short time, to prevent the axis/load from
drop/fall.
Mass moment of inertia of the brake
Unit: g cm^2
This value is affected by automatic scanning.
