Emergency stop
Note: The user is responsible for installing the emergency stop devices and all the
additional devices needed for the emergency stop to fulfil the required emergency
stop category classes. For more information, contact your local ABB representative.
The emergency stop signal is to be connected to the digital input which is selected as
the source for the emergency stop activation (par.
10.13 Em stop off3 or 10.15 Em
stop off1 ). Emergency stop can also be activated through fieldbus ( 02.22 FBA main
cw ).
Note: When an emergency stop signal is detected, the emergency stop function
cannot be cancelled even though the signal is cancelled.
Encoder support
The program offers support for two encoders (or resolvers), encoder 1 and 2.
Multiturn encoders are supported only as encoder 1. Three optional interface
modules are available:
• TTL Encoder Interface FEN-01: two TTL inputs, TTL output (for encoder
emulation and echo) and two digital inputs for position latching
• Absolute Encoder Interface FEN-11: absolute encoder input, TTL input, TTL
output (for encoder emulation and echo) and two digital inputs for position latching
• Resolver Interface FEN-21: resolver input, TTL input, TTL output (for encoder
emulation echo) and two digital inputs for position latching.
• HTL Encoder Interface FEN-31: HTL encoder input, TTL output (for encoder
emulation and echo) and two digital inputs for position latching.
The interface module is connected to drive option Slot 1 or 2. Note: Two encoder
interface modules of the same type are not allowed.
Settings
Parameter groups 91 Absol enc conf (page 225 ), 92 Resolver conf (page 228 ) and 93
Pulse enc conf (page 228 ).
Energy optimizer
The energy optimizer optimizes the flux so that the total energy consumption and
motor noise level are reduced when the drive operates below the nominal load. The
total efficiency of the drive system can be improved by 1…10% depending on load
torque and speed.
The energy saving tools calculate the energy saved in kWh and in local currency, and
as reduction in CO
2
emissions, all compared to the situation where the pump is
directly connected to the supply.
