152 PowerXL DG1 Series Adjustable Frequency Drives MN040004EN—March 2014 www.eaton.com
P7.6 117 Jog Reference 1, 2, 3, 4 RW
Defines the jogging speed selected with the digital input that can be programmed
for Jogging speed.
This parameter’s value is automatically limited between minimum and maximum
frequency (P1.1.1 and P1.1.2).
P7.7 156 Motor Pot Ramp Time 4 RW
Defines the speed of change of the motor potentiometer reference value.
P7.8 169 Motor Pot Ref Reset 4 RW
Defines how the reference signal is handled on shutting down frequency converter
output or powering down the frequency converter.
0 No reset
1 Memory reset in stop and power down
2 Memory reset in power down
P7.9 252 Start Mode 1, 2, 3, 4 RW
0 Ramp: The frequency converter starts from 0 Hz and accelerates to the set
reference frequency within the set acceleration time. (Load inertia or starting
friction may cause prolonged acceleration times.)
1 Flying start: The frequency converter is able to start into a running motor by
applying a small voltage to the motor to search for the frequency corresponding
to the speed the motor is running at. Searching starts from the maximum
frequency toward the actual frequency until the correct value is detected.
Thereafter, the output frequency will be increased/decreased to the set
reference value according to the set acceleration/deceleration parameters
Use this mode if the motor is coasting when the start command is given, with the
flying start.
P7.10 253 Stop Mode 1, 2, 3, 4 RW
0 Coasting: The motor coasts to a halt without any control from the frequency
converter after the Stop command. Slows based off the interia loss
1 Ramp: After the Stop command, the speed of the motor is decelerated
according to the set deceleration parameters. If the regenerated energy is high
and a faster deceleration is required, it may be necessary to use an external
braking resistor for faster deceleration
Enabled Normal stop: Ramp/Run
Disable stop: Coasting
