CG Drives & Automation,01-5326-01r5 Functional Description 127
11.5.3 Start/Stop settings [330]
Submenu with all the functions for acceleration,
deceleration, starting, stopping, etc.
Acceleration Time [331]
The acceleration time is defined as the time it takes for the
motor to accelerate from 0 rpm to nominal motor speed.
Communication information
Fig. 98 shows the relationship between nominal motor
speed/max speed and the acceleration time. The same is
valid for the deceleration time.
Fig. 98 Acceleration time and maximum speed
Fig. 99 shows the settings of the acceleration and
deceleration times with respect to the nominal motor speed.
Fig. 99 Acceleration and deceleration times
Deceleration Time [332]
The deceleration time is defined as the time it takes for the
motor to decelerate from nominal motor speed to 0 rpm.
Communication information
NOTE: If the Acc Time is too short, the motor is
accelerated according to the Torque Limit. The actual
Acceleration Time may then be longer than the value
set.
331 Acc Time
Default: 10.0 s
Range: 0–3600 s
Modbus Instance no/DeviceNet no: 43101
Profibus slot/index 169/5
EtherCAT and CANopen index (hex) 4c1d
Profinet IO index 19485
Fieldbus format Long, 1=0.01 s
Modbus format EInt
332 Dec Time
Default: 10.0 s
Range: 0–3600 s
Modbus Instance no/DeviceNet no: 43102
Profibus slot/index 169/6
EtherCAT and CANopen index (hex) 4c1e
Profinet IO index 19486
Fieldbus format Long, 1=0.01 s
Modbus format EInt
NOTE: If the Dec Time is too short and the generator
energy cannot be dissipated in a brake resistor, the
motor is decelerated according to the overvoltage
limit. The actual deceleration time may be longer than
the value set.
