ACSD-66/80 Digital Brushless AC S ervo D rive system - Ref.1609
Function Cutoff frequency of the first-order low-pass filter after the
velocity feedback.
Valid values 0 (the filter is not applied) ... 4 000 Hz.
Default value 800 Hz.
Function Determines the value of the acceleration ramp applied to
the velocity command. Setting it with a zero value means
that no ramps will be applied.
Valid values 0.0 ... 400.0 rpm/ms.
Default value 0.0 rpm/ms.
Function In emergency stop. If the bus voltage drops or there is a
power outage for the unit in the acceleration, deceleration or
constant power mode, The drive will always issue an E.003
or E.307 error and will enter into a dynamic braking sequence
without warning the CNC (DV32.13=0) or sending the
warning “WarningMainsLine” (DV31.10) to the CNC two
seconds before (DV32.13=1. It stops with the emergency
ramp until its speed is zero as long as the mechanical energy
stored in the motor allows it. Therefore, it limits the command
acceleration for stopping the motor.
