Siemens Building Technologies SED2 variable speed drives CM1U5192en
HVAC Products Programming 01.2002
6.3.6 OFF functions
This command (by eliminating the ON command) stops the variable speed drive within
the selected ramp-down time.
Parameters to change the ramp-down time: See P1121.
The ON and the consecutive OFF1 command must have the same source.
If the ON/OFF1 command is set for more than one digital input, only the last set
digital input is valid, e.g., DIN3 is enabled.
This command causes a free coasting of the motor to standstill (impulses for the power
section of the VSD are disabled).
The OFF2 command may have one or several sources. By default, the OFF2 command
is set to BOP/AOP. This source remains even if other sources are defined by one of
the parameters P0700 to P0708.
6.3.7 Control types
The different control types of the SED2 control the relationship between the motor
speed and the voltage supplied by the VSD. Below is a summary of the available
control types.
Can be used for variable or constant torque applications such as delivery systems and
positive displacer pumps.
This factory-set control mode can be used to improve performance and dynamic
behavior of the motor.
This factory-set control mode can be used for variable torque load such as fans and
pumps.
Refer to the engineering manual for information on this control mode.
This function automatically increases or decreases the motor voltage to locate the
lowest possible energy consumption. This control mode is enabled as soon as the
default setpoint speed is reached.
There is no slip compensation or resonance smoothing. The Imax controller relates to
voltage instead of frequency.
A combination of P1300 = 1 and P1300 = 5.
6.3.8 Communication
A serial interface RS485 is integrated. A RS232 interface is integrated in the optional
door mounting set for BOP/AOP.
See section 9.1 Options.
USS, P1, and N2 protocols are implemented as part of the series.
For detailed information, refer to the engineering manual.
