F1_RED.SEL
Parameter of MOTOR_1_FIELD -function block.
( S8/16 )
Enables field heating function for the motor when RUN-command is not active.
The function is activated 10 s after the RUN-command has been removed.
0 = DISABLE
1 = ENABLE.

F1_RED.REF
Parameter of MOTOR_1_FIELD-function block.
( S8/16 )
Field current reference when field heating function is active or when the motor is at
standstill. Default is 30% of nominal value.

OPTI.REF_GAIN
Parameter of MOTOR_1_FIELD_OPTIONS-function block.
( S8/16 )
Used in OPTI-TORQUE function. Gain factor used to multiply torque reference when field
current reference, F1_CURR_REF (11301), is calculated. Field current reference is
calculated from torque reference:
Field current reference = OPTI.REF_GAIN * torque reference / 98.

OPTI.REF_MIN_L
Parameter of MOTOR_1_FIELD_OPTIONS-function block.
( S8/16 )
Used in OPTI-TORQUE function. Minimum field level when OPTI_TORQUE function is
selected with FIELD_MODE (1001) parameter.
Default value is 15% of nominal field current. See next parameter.

OPTI.REF_MIN_TD
Parameter of MOTOR_1_FIELD_OPTIONS-function block.
( S8/16 )
Used in OPTI-TORQUE function. Time delay for minimum field indication. The field
reference
can’t be below the limit
OPTI.REF_MIN_L
longer than this time when
OPTI_TORQUE function is active or when field reversal is done

REV.REV_HYST
Parameter of MOTOR_1_FIELD_OPTIONS-function block.
( S8/16 )
Used in field reversal function. Hysteresis for actual field current comparator. During field
reversal output of the comparator will produce the flag FIELD1_REV_ACK located in
FEX_STATUS (11203)). Hysteresis is needed to avoid possible noise and offset of the
field current signal to affect the FIELD1_REV_ACK.
