±TORQUE_PRODUCT_
CURRENT_MAX rpm
The output of the speed regulator is a torque demand given as a
percentage of rated motor torque. This is then modified to account for
changes in motor flux if field weakening is active, and then used as the
torque producing current reference.

±TORQUE_PROD_
CURRENT_MAX %
The torque demand can be derived from the speed controller and/or the
torque reference and offset. The units of the torque demand are a % of
rated torque.

The current feedback signal is derived from internal current
transformers. It is used for closed loop control and indication of the
armature current, and to initiate motor protection.

The average measured DC output voltage seen across the drive A1 and
A2 terminals or the average measured DC output voltage seen across
the motor. Selected by Pr 5.14.
The armature voltage feedback has a resolution of 10-bit plus sign.

These parameters are controlled by the drive sequencer as defined in
Menu 6. They select the appropriate reference as commanded by the
drive logic. di11 (Pr 0.46, 1.11) will be active if a run command is given,
the drive is enabled and the drive is ok. This parameter can be used as
an interlock in a Onboard PLC or SM-Applications program to show that
the drive is able to respond to a speed or torque demand.

Contains the last 10 drive trips. tr01 (Pr 0.51, 10.20) is the most recent
trip and tr10 (Pr 0.60, 10.29) the oldest. When a new trip occurs all the
parameters move down one, the current trip is put in tr01 (Pr 0.51,
10.20) and the oldest trip is lost from the bottom of the log. Descriptions
of the trips are given in Table 13-1 on page 167. All trips are stored,
including HF trips numbered from 20 to 29. (HF trips with numbers from
1 to 16 are not stored in the trip log.) Any trip can be initiated by the
actions described or by writing the relevant trip number to Pr 10.38. If
any trips shown as user trips are initiated the trip string is "txxx", where
xxx is the trip number.
