C033 Dual Ramp; C034 Eso Ramp - Zener MSC-3 Instruction Manual

C033 DUAL RAMP

Available Choices:
• Press  once to begin.
• Use the ▲ / ▼ buttons to enable or disable the menu lock.
• Press  to confirm the choice.
When this feature is enabled, the C032 S TIME parameter specifies the acceleration and deceleration
below the C010 MIN Hz setting. Above the C010 MIN Hz setting, the acceleration and deceleration
times are as per C030 ACCEL TIME and C031 DECEL TIME respectively. Note that there is no
C032 S TIME when this feature is enabled. The following graph demonstrates this feature.

C034 ESO RAMP

Range: 0.5...600.0 seconds
• Press  to edit the value.
• Press ▲/ ▼ to make changes to the value.
• Press  to accept the new value OR
• Press ESC to abandon the value change.
When the drive is operating in ESO mode it will use the C034 ESO RAMP setting for acceleration and
deceleration instead of the C030 ACCEL TIME and C031 DECEL TIME settings. The ESO Ramp time is
the time taken for the motor to go from zero speed up to motor rated speed (assuming minimum C032 S
TIME). A MSC-3 with the B03 MOTOR Hz set to 50 Hz and an C034 ESO RAMP set to 10 seconds will
take 10 seconds to go from 0Hz to 50Hz.
