300716 Torque constant invalid POWER ON
POWER ON
Drive only ramps up to ramp-up state 2
1. Torque constant MD 1113 has a value that is less than or equal to 0.
2. The ratio of torque constant MD 1113/number of pole pairs MD 1112 is greater than 70.
Enter a valid value in machine data MD 1113 “Torque constant”.
Applies as from SW 3
300717 Motor moment of inertia <= 0 POWER ON
POWER ON
Drive only ramps up to ramp-up state 2
Motor moment of inertia MD 1117 has a value that is less than or equal to 0.
Enter a valid value in machine data MD 1117 “Motor moment of inertia”.
Applies as from SW 3
300718 Calculation delay error, I controller POWER ON
POWER ON
Drive only ramps up to ramp-up state 2
Input error in calculation delay timer MD 1101
Correct input error in calculation delay timer MD 1101.
Applies for SW 3 only
300719 Error motor code number POWER ON
POWER ON
Drive only ramps up to ramp-up state 2
One of the motor code numbers is illegal (P–96 or P–238)
Additional information
Motor fault (1 or 2)
S Change motor code number
S Save BOOT drive
S Repeat ramp-up
Applies for SW 3 only
300719 Motor delta not parameterized POWER ON
POWER ON
Drive only ramps up to ramp-up state 2
During activation of the star-delta changeover by drive MD1013, the motor delta (motor2) is not para-
meterized.
Check or enter machine data for motor delta (motor 2).
Applies as from SW 4
300720 Maximum motor speed too high POWER ON
POWER ON
Drive only ramps up to ramp-up state 2
Maximum motor speed MD 1401 of speed controller clock pulse MD 1001 have too great a value.
Reduce maximum motor speed MD 1401 or set a smaller speed controller clock pulse MD 1001.
Applies for SW 3 only
