Retry torq.block
If the actuator is blocked in move (block outside the end position range), the actuator is tripped and
a “blocked in move” fault signal is set. The actuator continues to signal „ready“ since it can still be
operated into the opposite direction.
If the value for the „retry torq.block“ parameter is not equal to zero, the actuator is automatically
operated in the opposite direction (for a travel which corresponds to the end position range, but
not longer than 2 s) and the back in direction of the block. This happens until the block has been
overcome or the programmed number of tries has been reached.
Default setting is 0.
Rise time
The „rise time“ parameter accesses the integral frequency converter. The shorter the rise time the
faster the actuator reaches the specifi ed speed. The setting of the rise time infl uences the modu-
lating behavior. Longer rise times lead to higher modulating accuracy, which reduces the control
dynamics at the same time.
The setting range (in 0.1 s steps) is 0.1 s to 1 s for standard actuators, 0.1 s to 2 s for modulating
actuators.
Default setting is 0.5 s.
dc-brake
A value not equal to „0 %“ triggers the dc brake via the integral frequency converter. The higher the
value, the higher the dc braking current is set.
For a value of „0 %“, the speed of the motor is reduced as quickly as possible to a standstill via the
frequency converter. For nearly all operation points, this is the shortest time to achieve a standstill.
We therefore recommend maintaining the default settings.
Motor temperature warning
A warning is issued once the motor temperature has reached a preset value. A value between 0
and 155 °C can be set.
The warning signal can be provided via binary signal and fi eldbus protocol.
Default value is 135 °C.
This parameter is not available for the part-turn actuator 2SG5.
Motor temperature protection
The motor is equipped with full electronic motor protection against thermal damage. The motor pro-
tection is activated in the factory and can be disabled. To prevent accidental disabling, code 9044
has to be entered for acknowledgement.
Disabling the motor protection will void the warranty for the motor!
Motor heating
To prevent condensation while the motor is at standstill, the motor can be heated with DC current
when the heater is activated. The heating up depends on the difference between motor temperature
and ambient temperature.
The heater is switched off as standard.
If exposed to strong climatic fl uctuations, the actuator should be operated with the motor heater
switched on.
