Start-up

If the direction of rotation is selected as forward, check that the actual
speed (
/
) is
positive:
• If the actual direction of rotation is forward and the actual speed
negative, the phasing of the pulse encoder wires is reversed.
• If the actual direction of rotation is reverse and the actual speed
negative, the motor cables are incorrectly connected.
Changing the connection:
Disconnect the main power, and wait for 5 minutes for the intermediate circuit
capacitors to discharge. Do the necessary changes. Switch the power on and start the
motor again. Check that the estimated and actual speed values are correct.
• If the direction of rotation is selected as reverse, the actual speed
must be negative.
Note:
Resolver autotuning routines should always be performed after
resolver cable connection has been modified. Autotuning routines can
be activated by setting parameter
, and then setting parameter
. If the resolver is used with a permanent
magnet motor, an Autophasing ID run should be performed as well.
/
Stop the motor.
Set parameter
If the speed feedback cannot be used in motor control: In special
applications parameter
must be set to
TRUE.
Note:
Speed filtering needs to be adjusted especially when the
encoder pulse number is small. See section
on page
.
Emergency stop circuit
If there is an emergency stop circuit in use, check that the circuit
functions (emergency stop signal is connected to the digital input
which is selected as the source for the emergency stop activation).
