Parameter Units Level
39-FTL - Minimum Frequency in Torque Limit Hz L2
When the drive's output current exceeds the limits defined by 27-TLSEL, the motor will be decelerated at a
rate determined by 46-DECTL to the frequency programmed at this parameter. If this parameter is set to a
value greater than parameter 32-FMAX, TORQUE LIMITING WILL BE DISABLED.
41-RSEL - Ramp Selector L2
This parameter defines the acceleration and deceleration characteristics of the drive. The following table
outlines the possibilities:
42-ACC1 - Acceleration Ramp #1 s L1
Parameter 42-ACC1 defines the primary inverter response to an increase in speed command. It is adjustable
in 0.01 second increments from 0.1 to 600 sec. from zero to maximum frequency. The factory setting is three
(3) seconds.
43-DEC1 - Deceleration Ramp #1 s L1
Parameter 43-DEC1 defines the primary inverter response to a decrease in speed command. It is adjustable
in 0.01 second increments from 0.1 to 600 sec. from maximum to zero frequency. The factory setting is three
(3) seconds.
44-ACC2 - Acceleration Ramp #2 s L2
Parameter 44-ACC2 defines the secondary inverter response to an increase in speed command. It is
adjustable in 0.01 second increments from 0.1 to 600 sec. from zero to maximum frequency. The factory
setting is one (1) second.
45-DEC2 - Deceleration Ramp #2 s L2
Parameter 45-DEC2 defines the secondary inverter response to a decrease in speed command. It is
adjustable in 0.01 second increments from 0.1 to 600 sec. from maximum to zero frequency. The factory
setting is one (1) second.
46-DECTL - Torque Limit Response Time s L2
When the drive senses that the torque limit threshold has been exceeded, it takes immediate action. If
operating in the motoring mode, it begins to decelerate toward the value of 39-FTL. If operating in the
regenerative mode, it begins to accelerate toward the rotational speed to which it is being driven. In either
case, 46-DECTL governs the drive's response time.
47-DCBRK - DC Brake Time s L2
In the keypad or terminal input mode, after issuing a STOP command, the inverter ramps down to zero
speed and provides a holding DC current in the motor windings for the period set by 47-DCBRK. This
function is not available with zero (0) seconds set at 47-DCBRK or if the stopping performance is set for
coast.
If DCBRK set to 5.0 seconds and both the FWD and REV terminals activated simultaneously or if a
zero speed command is issued, DC current will be applied to the motor at zero speed until one, or
both terminals are de-activated.
DATA CODE DESCRIPTION
0 42-ACC1 and 43-DEC1 control drive acceleration and deceleration for both forward
and reverse operation. 44-ACC2 and 45-DEC2 are selected by input terminal ART.
To use ART, 21-MODE must be set for terminal strip start/stop control.
1 First set of ramps in the forward direction, second set of ramps in the reverse direction.
Terminal ART is inactive.
2 Dual slope linear ramp. Primary set of ramps control acceleration / deceleration when
12-FOUT less than the value programmed at 37-F6. Secondary set of ramps
control when 12-FOUT greater than 37-F6. Terminal ART is inactive.
3 "S" curve acceleration and deceleration. Terminal ART is inactive.
4 Performance same as code "0" except Coast-to-stop when STOP is commanded.
5 Performance same as code "1" except Coast-to-stop when STOP is commanded.
6 Performance same as code "2" except Coast-to-stop when STOP is commanded.
7 Performance same as code "3" except Coast-to-stop when STOP is commanded.
