300721 I0 motor > i-rated motor
Scan
POWER ON
Effect
Drive only ramps up to ramp-up state 2
Explanation
Motor no-load current (MD 1136) is greater than the rated current (MD 1103) of the motor.
S
Remedy
Change motor data
S
Save BOOT drive
S
Repeat ramp-up
Note
Applies for SW 3 only
300722 I0 motor > I-rated power section
Scan
POWER ON
Effect
Drive only ramps up to ramp-up state 2
Explanation
Connected motor too large for power section being used (continuous current MD 1108) because of its no-load
current (MD 1136).
Remedy
Change power section or motor
Note
Applies for SW 3 only
300723 STS configuration axially unequal
Scan
POWER ON
Effect
Drive only ramps up to ramp-up state 2
Explanation
On 2-axis modules, the configuration of the control set MD 1003 must be identical for both axes.
Remedy
Make the configuration of the control set identical for both axes.
Note
Applies as from SW 3

Scan
POWER ON
Effect
Drive only ramps up to ramp-up state 2
Explanation
FDD: MD 1112 is not correct.
MSD: MD 1134 or MD 1400 is not correct.
Remedy
Eliminate error on inputting the above machine data.
Note
Applies as from SW 4
300725 Number of encoder marks = 0
Scan
POWER ON
Effect
Drive only ramps up to ramp-up state 2
Explanation
The number of encoder marks MD 1005 has the value 0.
Remedy
Eliminate error when entering the number of encoder marks MD 1005.
Note
Applies as from SW 3
300726 Voltage constant = 0
Scan
POWER ON
Effect
Drive only ramps up to ramp-up state 2
Explanation
The voltage constant MD 1114 has a value less than or equal to zero.
Remedy
Eliminate error on inputting the voltage constant MD 1114.
Note
Applies as from SW 4
