#3098 IDD CauThresholdSp
[C80]
Set the threshold so that "Z38 Insulation deterioration wrn 0001" could occur.
When performing the insulation deterioration detection and the detected value falls below the parameter set-
ting value, "Z38 Insulation deterioration wrn 0001" occurs.
If "0" is set, the standard value (100[0.1 megohm]) will be applied.
---Setting range---
0 to 300 (0.1 megohm)
#3099 IDD ChgThresholdSp
[C80]
Set the threshold so that "Z38 Insulation deterioration wrn 0002" could occur.
When performing the insulation deterioration detection and the detected value falls below the parameter set-
ting value, "Z38 Insulation deterioration wrn 0002" occurs.
If "0" is set, the standard value (10[0.1 megohm]) will be applied.
---Setting range---
0 to 300 (0.1 megohm)
#3101 sp_t 1
Set the acceleration/deceleration time constant with S command (speed operation mode) when gear 00 is
selected. Set the linear acceleration/deceleration time up to limit rotation speed (slimit1). Set the short time
constant that the motor torque at acceleration is always saturated, however, when an abnormal noise or V-
belt slip occurs, increase the time constant.
---Setting range---
0 to 30000 (ms)
#3102 sp_t 2
Set the acceleration/deceleration time constant with S command (speed operation mode) when gear 01 is
selected. Set the linear acceleration/deceleration time up to limit rotation speed (slimit2). Set the short time
constant that the motor torque at acceleration is always saturated, however, when an abnormal noise or V-
belt slip occurs, increase the time constant.
---Setting range---
0 to 30000 (ms)
#3103 sp_t 3
Set the acceleration/deceleration time constant with S command (speed operation mode) when gear 10 is
selected. Set the linear acceleration/deceleration time up to limit rotation speed (slimit3). Set the short time
constant that the motor torque at acceleration is always saturated, however, when an abnormal noise or V-
belt slip occurs, increase the time constant.
---Setting range---
0 to 30000 (ms)
#3104 sp_t 4
Set the acceleration/deceleration time constant with S command (speed operation mode) when gear 11 is
selected. Set the linear acceleration/deceleration time up to limit rotation speed (slimit4). Set the short time
constant that the motor torque at acceleration is always saturated, however, when an abnormal noise or V-
belt slip occurs, increase the time constant.
---Setting range---
0 to 30000 (ms)
#3105 sut
Set the speed deviation rate with respect to the commanded speed, at which the speed reach signal will be
output.
It will be 15% when set to "0".
If the speed deviation is smaller than 45r/min, it will be set as 45r/min.
---Setting range---
0 to 100 (%)
