5.2 PARAMETER REGULATION
In addition to the input configuration, parameter modification is made either by ZAPI
upon Customer specifications, or directly by the Customer using the programming
console. The following parameters can be modified:
NAME FUNCTION
1 ACC. DELAY: Determines the acceleration ramp.
2 RELEASE BRAKING: Controls the deceleration ramp when the running request
is released.
3 INVERSION BRAKING: Controls the deceleration ramp when an inversion of the
direction is requested.
4 CURVE BRAKING: Controls the deceleration ramp when RV1 is held active
during running (see 4.1.).
5 SPEED LIMIT BRAKING:Controls the deceleration ramp when the accelerator
pedal position is changed (but not completely released).
6 RV1: First speed reduction.
7 RV2: Second speed reduction.
8 MAX SPEED FORW: This is the maximum speed in forward direction; this
speed is got by weakening the field current after the full
conduction on the rotor has been reached; when the
parameter is programmed to LEVEL = 0, if the motor is in
full conduction, the field current will not be decreased
under the nominal value (low speed).
9 MAX SPEED BACK: This is the maximum speed in backward direction; this
speed is got by weakening the field current after the full
conduction on the rotor has been reached; when the
parameter is programmed to LEVEL = 0, if the motor is in
full conduction, the field current will not be decreased
under the nominal value (low speed).
10 CREEP SPEED: Minimum speed.
11 MAX CURRENT: Maximum armature current of the controller.
12 FIELD NOM. CURR.: Nominal field current: this is the minimum field current when
the accelerator is in the range from 0% to 60% (no full
conduction on the armature); must be adjusted to the nomi-
nal value of field current of the motor (stated by the motor
manufacturer on the motor identification plate).
13 ARMA NOM. CURR.: This is the nominal armature current; this establishes an
armature current level above which the field current is at
least at its nominal value (FIELD NOM. CURR.) or more,
regardless of the accelerator position.
14 WEAK DROPOUT: This parameter establishes an armature current level
above which the field current is proportionally increased
up to the nominal value.
