Chapter 12 Description of Parameter SettingsME300
12.1-01-7
Use suitable brake resistors (refer to Chapter 07 Optional Accessories) to decelerate in a short
time and prevent over-voltage.
When you enable Pr.01-24–Pr.01-27 (S-curve acceleration and deceleration begin and arrival
time), the actual acceleration and deceleration time are longer than the setting.
JOG Frequency
Default: 6.00
Settings 0.00–599.00 Hz
You can use both the external terminal JOG and F1 key on the optional keypad KPC-CC01 to set
the JOG function. When the JOG command is ON, the AC motor drive accelerates from 0 Hz to
the JOG frequency (Pr.01-22). When the JOG command is OFF, the AC motor drive decelerates
from the JOG frequency to stop. The JOG acceleration and deceleration time (Pr.01-20, Pr.01-21)
are the time to accelerate from 0.0 Hz to the JOG frequency (Pr.01-22). You cannot execute the
JOG command when the AC motor drive is running. When the JOG command is executing, other
operation commands are invalid.
First / Fourth Acceleration / Deceleration Frequency
Default: 0.00
Settings 0.00–599.00 Hz
This function does not require the external terminal switching function; it switches the
acceleration and deceleration time automatically by the Pr.01-23 setting. If you set the external
terminal, it is based on the external terminal first, and not on Pr.01-23.
When using this function, set the S-curve acceleration time to 0.
