• The following shows the time chart when the UP/DOWN commands are used.
U = UP (accel) status
D = DOWN (decel) status
H = HOLD (constant speed) status
U1 = During clamp at upper limit speed even in UP status
D1 = During clamp at lower limit speed even in DOWN status
Notes:
1. When the UP/DOWN commands are used, set the Sn-04 1st digit. (frequency reference selection) as
shown below.
Set 1st digit = 0 without fail.
Setting 1st digit = 1 disables the UP/DOWN commands.
2. When the UP/DOWN commands are selected, the upper limit speed is set disregarding frequency reference.
Upper limit speed = maximum output frequency (Cn-02) × frequency reference upper limit (Cn-14)
3. The largest value among the minimum output frequency (Cn-07), the frequency reference lower limit
(Cn-15), and main frequency reference input from the control circuit terminal VIN or AIN is employed as the
lower limit speed.
4. By inputting the FWD/REV run commands, operation is started at the lower limit speed even if the
UP/DOWN command is not asserted. When the power supply is turned OFF in the HOLD status, the
held output frequency is stored. Therefore, by inputting the FWD/REV run commands in the HOLD
status continuously after the power supply is turned ON, operation is performed at the stored
output frequency.
5. When the jog run command is asserted during run by UP/DOWN commands, the jog run command
has priority.
