300733 Motor no-load voltage invalid
Scan
POWER ON
Effect
Drive only ramps up to ramp-up state 2
Explanation
The motor no-load voltage MD 1135 is less than or equal to zero or greater than rated motor voltage MD 1132 or
greater than 450 x MD 1400/MD 1142.
With
MD 1400: Rated motor speed
MD 1142: Speed at start of field weakening
Remedy
Eliminate error on inputting
S
Rated motor voltage MD 1132
S
Rotor zero-speed voltage MD 1135
S
Rated motor speed MD 1400
S
Threshold speed field weakening MD 1142.
S
Motor no–load current MD 1136
Note
Applies as from SW 4
300734 Motor no-load current <= 0
Scan
POWER ON
Effect
Drive only ramps up to ramp-up state 2
Explanation
Motor no-load current MD 1136 is less than or equal to zero.
Remedy
Eliminate error on inputting the motor no-load current MD 1136.
Note
Applies as from SW 4
300735 Field weakening speed <= 0
Scan
POWER ON
Effect
Drive only ramps up to ramp-up state 2
Explanation
Field weakening speed MD 1142 is less than or equal to zero.
Remedy
Eliminate error on inputting the field weakening speed MD 1142.
Note
Applies as from SW 4
300736 Lh characteristic invalid
Scan
POWER ON
Effect
Drive only ramps up to ramp-up state 2
Explanation
Upper speed on the Lh characteristic MD 1143 is less than or equal to field weakening speed MD 1142 or gain of
Lh characteristic MD 1144 is less than 100.
Remedy
Eliminate error on inputting
S
Upper speed of the Lh characteristic MD 1143
S
Gain of the Lh characteristic MD 1144
S
Field weakening speed MD 1142.
Note
Applies as from SW 4
300740 Parameterization error
Scan
POWER ON and cyclic
Effect
Drive only ramps up to ramp-up state 2 or pulse suppression and motor runs down
Explanation
Division error has occurred because of illegal parameter combination
Additional information: none
S
Remedy
Check parameters and correct
S
Save BOOT
S
Repeat ramp-up
Note
Applies as from SW 3
