Keypad:
Start and stop with
and keys (Standard keypad)
Start and stop with
/ and keys (Optional multi-function keypad)
External signals (digital inputs): Forward (Reverse) rotation, stop command (capable of 3-wire
operation), (digital input) coast-to-stop command, external alarm, alarm
reset, etc.
Link operation: Operation through RS-485 or field bus (option) communications
Start/stop operation
Switching operation command: Remote/local switching, link switching
Keypad: Settable with and keys
External volume: Can be set with external frequency command potentiometer.(1 to 5 kΩ 1/2 W)
Analog input: 0 to ±10 VDC (±5 VDC)/ 0 to ±100% (terminals [12] and [V2]),
0 to +10 VDC (+5 VDC)/ 0 to +100% (terminals [12] and [V2])
("+1 to +5VDC" can be adjusted with bias and analog input gain.)
+4 to +20 mA DC/ 0 to 100% (terminal [C1])
0 to +20 mA DC/ 0 to 100% (terminal [C1]) *11
UP/DOWN operation: Frequency can be increased or decreased while the digital input signal is ON.
Multi-frequency: Selectable from 16 different frequencies (step 0 to 15)
Pattern operation: Automatic operation according to the preset operating time, rotational direction,
acceleration/deceleration time and reference frequency. Up to 7 stages can be set.
*12
Link operation: Frequency can be specified through RS-485. (Standard setting)
Frequency setting: Two types of frequency settings can be switched with an external signal
(digital input). Remote/local switching, link switching
Auxiliary frequency setting: Inputs at terminal [12], [C1] or [V2] can be added to the main setting as
auxiliary frequency settings.
Operation at a specified ratio: The ratio can be set by analog input signal.
Inverse operation
: Switchable from "0 to +10 VDC/0 to 100%" to "+10 to 0 VDC/0 to 100%" by external command.
: Switchable from "4 to +20 mA DC/0 to 100%" to "+20 to 4 mA DC/0 to 100%" by external command.
: Switchable from "0 to +20 mA DC/0 to 100%" to "+20 to 0 mA DC/0 to 100%" by external command. *11
Pulse train input
(standard):
Pulse input = Terminal [X7], Rotational direction = general terminal
Complementary output: Max. 100 kHz,
Open collector output: Max. 30 kHz
Frequency setting
Pulse train input
(option):
PG interface option CW/CCW pulse, pulse + rotational direction
Complementary output: Max. 100 kHz,
Open collector output: Max. 25kHz
Setting range: Between 0.00 and 6000 s
Switching: The four types of acceleration/deceleration time can be set or selected individually
(switchable during operation).
Acceleration/deceleration pattern: Linear acceleration/deceleration, S-shape acceleration/deceleration
(weak, free (strong)), curvilinear acceleration/deceleration
(acceleration/deceleration max. capacity of constant output)
Deceleration mode (coast-to-stop): Shutoff of the run command lets the motor coast to a stop.
Control
Acceleration/
deceleration time
Forcible stop deceleration time: Deceleration stop by the forcible stop STOP.
