Setting of acceleration/deceleration time and acceleration/deceleration pattern
4.9.2 Motor starting speed (Pr.13)
The above parameters can be set when Pr.160 Extended function display selection = "0". (Refer to page 182)
When a value exceeding 3000 r/min is set, the rotation speed will be limited at 3000 r/min.
Also, when an S-PM geared motor is used, the maximum setting value differs depending on the drive unit capacity. (0.2 to 2.2K: 12000 r/min, 3.7K: 8000 r/
min)
NOTE
Under position control, Pr.7, Pr.8, Pr.44, Pr.45, Pr.147, Pr.791, and Pr.792 are invalid. (Refer to page 88)
Parameters referred to
Pr.10 Coasting speed Refer to page 131
Pr.29 Acceleration/deceleration pattern selection Refer to page 129
Pr.125, Pr.126 (speed setting gain speed) Refer to page 173
Pr.178 to Pr.184 (input terminal function selection) Refer to page 138
The speed at which the motor starts running can be set.
Set the deadband in the low-speed range to eliminate noise and offset deviation when setting a speed with analog
input.
Parameter
number
Name Initial value Setting range Description
13 Starting speed
15r/min 0 to 4800r/min
The speed where the motor starts
running.
The speed where the PM motor starts running can be set.
While the speed command is less than the Pr.13 Starting speed
setting, the motor is stopped when a start command (forward or
reverse) is input.
When the speed command reaches the setting value or higher, the
PM motor accelerates according to the Pr.7 Acceleration time setting.
NOTE
Under position control, the starting speed is invalid.
When an MM-GKR motor is used, the operation for stopping (zero speed control or servo lock) can be selected in
Pr.802 Pre-excitation selection (brake operation selection).
When an S-PM geared motor is used, the DC injection brake operation is applied.
CAUTION
Note that when Pr.13 is set to any value equal to or lower than Pr.2 Minimum setting, simply turning ON the start
signal will run the motor at the preset speed even if the command speed is not input.
