4 Start-Up Programming & Operation
Multi-Function Analog Outputs
The H4 parameters assign functions to analog output terminals FM and AM. Select the function for these terminals by
entering the last three digits of the desired U monitor. For a list of analog output functions, refer to
page 207.
Accel/Decel Ramp and Jerk Settings
■
Acceleration and deceleration ramps are set using the C1- parameters. Use the C2- parameters to adjust the jerk
at the start of acceleration or deceleration.
Figure 39 explains how accel/decel ride and jerk settings can be used to adjust the ride profile.

Units used to set the acceleration and deceleration ramp as well as the Jerk function change with the setting of parameter
o1-03.
Elevator Emergency Stop
■
Start condition for Elevator Emergency Coast to Stop
An emergency coast to stop is performed when the Up or Down command is cleared and all of the following conditions
are met.
• Parameter b1-03 (Stopping Method Selection) is set to 4.
• Parameter d1-18 (Speed Reference Selection Mode) is set to 0 or 3.
• Parameter b1-01 (Speed Reference Selection) is set to 1.
• The Up/Down command is cleared and U1-05 (Speed Feedback) is equal to or greater than S1-26 (Emergency Stop
Start Level).
